Active graphics
- you might add additional/optional columns for the onmouseover and onmouseout attributes - simply have a look at this:

http://www.mrbbc.org/files/de/cloudlevels.htm

- you needn't understand what the text means to figure out how probably you could use JavaScript with image maps.

- But don't be overhasty. I think perhaps one column would be enough; for example if you make a tooltip, onmouseover will call a function that displays the tooltip, and onmouseout simply calls the counterpart that hides it. It should be first discussed whether there should be elementary JavaScript functions as a part of MediaWiki... --Mr. B.B.C. 16:49, 11 January 2007 (UTC)

Change image on mouseover
I needed this functionality so I modified this extension to add it. It is a pretty nasty hack but it does the job for me. Based on [|this tutorial]. I modified version 1.12, will upload if anyone is interested. --Jackocleebrown 17:56, 12 March 2009 (UTC)

Does not work in Templates
Seems, the extension does not work in templates. If I write in a template:

this is the result:

I think the extension is too early and interprets the brackets as signs instead of waiting for the replacement of the brackets with the parameter's content. If you omit the | it's even worse, then the whole page is broken. Am I right or do I make a mistake? --Slomox 17:30, 11 January 2007 (UTC)


 * I checked this, but I was able to use without problems in templates. jeroenvrp 02:58, 14 January 2007 (UTC)


 * You don't see <imagemap&gt;: invalid title in link at line 4 in the above example? --:Slomox:: &gt;&lt; 16:48, 15 January 2007 (UTC)


 * You can use it in a template, but only without parameters. JePe 20:07, 15 January 2007 (UTC)

Actually, if you use any curly braces at all, you can't even submit or preview the page. This also rules out any magic words. – Minh Nguyễn (talk, contribs) 05:26, 17 January 2007 (UTC)

If it was possible to use template parameters in this it would make replacing existing template CSS hacks much easier. 131.111.195.8 18:08, 17 January 2007 (UTC)


 * Just wanted to note that using as part of the image name also doesn't work.  Trying to develope an imagemaped element table at Wikipedia:Template talk:Elementbox header.  I'll just use a single elements name while putting together the long list of coordinates, but this needs to be fixed if it's to be usefull for this particular (and other) applications.  Otherwise, this is Great, especially the auto coordinat resizing! --D0li0 04:27, 23 January 2007 (UTC)

Does not work in Opera (round missing)
The coordinates are rendered as double values (e.g. ) which is useless and causes errors in some browsers. For example, in Opera all circle areas are broken. Please  all coordinates. Thank you. --TM


 * I checked it in Konqueror 3.5.5, Firefox 2.0.0.1 and the Opera 9.1, all on Linux. I can confirm that the imagemap does not work correctly in Opera. Konqueror and Firefox work great. Anyhow I really like to thank the developer who made this possible, the possibilities are really great with this extension. jeroenvrp 03:06, 14 January 2007 (UTC)

Polygons
How polygons should be described? Can you give an example? I tried to define Display and Keyboard on the example, but it does not work, probably coordinates are wrong :( Maximaximax 10:10, 16 January 2007 (UTC) PS. Polygons I created with Map This. Maximaximax 10:14, 16 January 2007 (UTC)

Look at the example. I made 2 polygons - for display and keyboard, but they are wrong - only keyboard is shown and in wrong place:

Output of this example:

What is also strange - on the original example (with circle and square) it shows only display but no keyboard: Output of this example:


 * I can confirm this. jeroenvrp 12:42, 18 January 2007 (UTC)


 * So, can anybody help me? Explain what to do or fix the plugin? Maximaximax 07:39, 21 January 2007 (UTC)

This appears to work:

Things to note:
 * poly coords do not take commas.
 * poly-s are defined prior to any other shapes
 * the image is left full-size

Once you get past the documentation problem involving commas, the problem is that the script is not re-initializing its list of coordinates prior to parsing poly coordinates. Thus, when parsing a poly it starts with the previous shape's coordinate list and adds the poly's coordinates to it. If you leave the image full-size, then each subsequent poly is the aggregate of all the previous poly's, but you don't generally notice because the earlier ones are on top. If you're scaling, then each subsequent poly starts with a scaled version of the previous poly</tt>, which gets kinda weird.

If you're interested in fixing it, you might insert in ImageMap_body.php</tt> right after case 'poly': the line $coords = array;

Mine now looks like this (lines 140-146) }                                       break; case 'poly': $coords = array; /*<<<FIX*/ $coord = strtok( " \t" ); while ( $coord !== false ) { $coords[] = $coord;

Piped links
The documentation says that the format  should work. However, once I place that in the call to imagemap, the extension has the same issue that we've seen with curly braces: you can't submit or preview the page. – Minh Nguyễn (talk, contribs) 05:29, 17 January 2007 (UTC)

Longdesc not working
In my screen reader JAWS, when I encounter an image with a long description, I can press enter to hear the description. That doesn't work at the moment - when using the example on the page, I get with the extra " " in the address. I don't see a problem with using the extension otherwise as long as sensible image descriptions are used. Graham87 07:22, 17 January 2007 (UTC)
 * Filed as bug 8667. Graham87 03:25, 18 January 2007 (UTC)

Image description link size

 * Would it be possible to add a way to reduce the size of the image description link? Currently existing 'clickable images' using template hacks are generally used for small icons. When the ImageMap is applied to these the link for the image description page winds up covering a large part of the image. The sister projects links on the en-wikip 'Main Page' are a good example of this. --12.42.50.51 15:27, 17 January 2007 (UTC)


 * Also, it would be nice if it were possible to use:

or


 * Currently you have to specify a rectangle, circle, or polygon region before you can set a default for the rest of the image... but 99.99% of the time people are going to want the entire image to be clickable and link to a single location. --12.42.50.51 15:34, 17 January 2007 (UTC)

 * The above worked fine for me in Firefox but in I.E. 7.0 the hyperlink does not work (you can't click through to the page specified). Ross Allen 20:12, 21 May 2008 (UTC)
 * Another issue, if 'imagemap' is used within a template it does not seem to be able to handle parameters. That is, at the end of the call to  . – Minh Nguyễn (talk, contribs) 19:29, 17 January 2007 (UTC)

After I installed the imagemap extension, when I was first trying to use it, an kind of ugly 'i' info button showed up on top of the image. It took a while to figure out how to get rid of this 'i' since the syntax example provided in the extension is incorrect (I think). At the bottom of the syntax example it reads:
 * i Info button on the image

desc bottom-left

However, in the image example, there is no 'i' button in the lower lefthand corner of the image. If I understand this extension correctly, either the syntax example should be changed to

desc none

or the example should correctly reflect the syntax example, and show the 'i' button in the lower lefthand corner.

Inline use
First of all, thanks to TimStarling for this fantastic and long-awaited extension! It is really handy. However, there is one (minor) problem with it: It can't be used inline. If I want a line that links a country's flag to the country (instead of the image, of course), then write something next to the flag, that text will come one liner further down. See what I mean here:


 * Nauru

The possibility to use it in templates would also be handy. Otherwise it is excellent. Thanks for making it! Jon Harald Søby 20:16, 18 January 2007 (UTC)

Try floating the image:


 * Nauru

It's not very flexible, but it works for displaying flags next to countries' names.

– Minh Nguyễn (talk, contribs) 20:01, 20 January 2007 (UTC)


 * Inline use is possible with this extension. It is explained in the German Wikipedia: see here and here. --WIKImaniac 13:09, 3 August 2007 (UTC)


 * If 8788 and 8718 are fixed, then this should be cleared up without the German Wikipedia approach. In the meanwhile, that display:inline approach looks pretty good. Michael Daly 21:26, 5 August 2007 (UTC)

Dutch Translation
I don't know were or how to post it so I put it here, you are free to movie to another more appropiate location:

I have made a Dutch translation for the ImageMap extension which could be incorporated in a later version: /* Dutch (Erik van Berkum) */ 'nl' => array( 'imagemap_no_image'            => '&lt;imagemap&gt;: moet een afbeelding specificeren in de eerste  regel', 'imagemap_invalid_image'        => '&lt;imagemap&gt;: afbeelding bestaat niet of er is een spelfout', 'imagemap_no_link'              => '&lt;imagemap&gt;: ongeldige link gevonden aan het eind van de regel $1', 'imagemap_invalid_title'        => '&lt;imagemap&gt;: ongeldige titel in de link bij regel $1', 'imagemap_missing_coord'        => '&lt;imagemap&gt;: niet genoeg coordinaten voor een vorm bij regel $1', 'imagemap_unrecognised_shape'   => '&lt;imagemap&gt;: de vorm wordt niet herkent bij regel $1, elke lijn moet starten met een van de volgende: '.								   'default, rechthoek, circel or poly', 'imagemap_no_areas'             => '&lt;imagemap&gt;: op zijn minst een gebied moet gespecificeerd worden', 'imagemap_invalid_coord'        => '&lt;imagemap&gt;: ongeldige coordinaat bij regel $1, het moet een nummer zijn', 'imagemap_invalid_desc'        => '&lt;imagemap&gt;: ongeldige desc specificatie, moet een van de volgende zijn: $1', 'imagemap_description'         => 'Over deze afbeelding', 'imagemap_desc_types'          => 'boven-rechts, beneden-rechts, bodem-links, boven-links, geen', ),
 * 1) Note to translators: keep the same order

Possible bug report
I've discovered why some of the click maps seem to be far too small: The pixel co-ordinates specified are for the original-sized image, not for the image as resized by this tag. Since this tag is itself resizing images, and since the image map coordinates come after the resize statement, shouldn't the co-ordinates refer to the transformed pixels rather than the original ones? 18:09, 23 January 2007 (UTC) Rawling from Wikipedia
 * Well, I've noticed this is explicitly referenced on the main page, so I'll just leave now. Hopefully this might explain it if, like me, someone else fails to notice... 18:36, 23 January 2007 (UTC) Rawling from Wikipedia

Could someone provide a list of the steps necessary to enable this extension.

Another imagemap variant
I've developed an ImageMap extension at the same time and published documentation before this was published. In my opinion I was ready before all of this was posted. This seems to be an accident or a mistake. I do not like to work at something another guy already coded. I searched all extension sources and MediaWiki and I've not found an imagemap extension at the end of January 2007. Than I started to write an extension at my own. The major benefit of my work compared to this imagemap extension is that using my extension a user can use kImageMapEditor to create imagemaps. This is just a huge benefit compared to this extension.

 * There is also Shannon McNaught's version that is older than yours or Tim's.
 * I'm currently writing a php program to convert a generic HTML file with <MAP>...</MAP> included into the map tag format that Tim's ImageMap extension uses. I have a bunch of wiki articles that use the older ImageMap format with files and this will allow me to convert them.  As well, it will allow me to convert files generated by generic Map editors for use with Tim's ImageMap.
 * I was also thinking of taking the two ImageMap extensions and merging them into a single extension so that one can use either format - external files with map data uploaded to the wiki (McNaught's)or imbedded map tags (Tim's). I wonder if there'd be any interest?  Michael Daly 19:24, 25 March 2007 (UTC)
 * I've done this as Extension:ImageMap (Alternate). Michael Daly 05:51, 5 May 2007 (UTC)

No image found: more information
I added the name of the image to the error message. Makes it easier to find the missing image.

// ImageMap_body.php $domDoc = DOMDocument::loadXML( $imageHTML ); $xpath = new DOMXPath( $domDoc ); $imgs = $xpath->query( '//img' ); if ( !$imgs->length ) { return self::error( 'imagemap_invalid_image' . ': ' . $image ); // change this line }


 * This fix will break the internationalization. The text 'imagemap_invalid_image' is the key to a table that contains the full text of the message in the user's language.  There is a better way to do this but it requires a change to the error messages. Michael Daly 07:09, 12 May 2007 (UTC)

MediaWiki 1.8.2
I found that it works in 1.8.2 also.


 * I get "Table 'wikidb.mw_cur' doesn't exist (localhost)" in MediaWiki 1.8.2 -- Adrianm, 28 February 2007


 * the cur table hasn't been used since the days of 1.4 - i find it unlikely this extension is using it (in fact, it does not appear to use any direct db access at all). So that error must be caused by something else. -- Duesentrieb ⇌ 10:26, 28 February 2007 (UTC)


 * thanks, I now get: "Class 'DOMDocument' not found", even though this class should be included in PHP 5 (I am using PHP 5.1.6) -- Adrianm, 2 March 2007

Eliminate Case Sensitive Shape Names
I added a couple of lines to ImageMap_body.php: here: $cmd = strtok( $line, " \t" ); $cmd = strtolower( $cmd ) ; and here: $shape = strtok( $shapeSpec, " \t" ); $shape = strtolower( $shape ) ;
 * 1) Handle desc spec
 * 1) ignore case
 * 1) Tokenize shape spec
 * 1) ignore case

to eliminate case sensitivity in the shape parameters - this to make it easier to convert from Shannon McNaught's older version of ImageMap to this one.

Thanks for the extension! Michael Daly 21:46, 7 March 2007 (UTC)

Fallback for mobile phones etc?
Just wondering how the image maps behave on less capable browsers like mobile phones etc. I'm a bit concerned that lists of links on Wikipedia are being replaced by image maps, without regard for browsers that can't render them (or in which clicking on a link in an image is basically impossible). If this is a valid concern, we might need a policy like "Every image map should be accompanied by a link to an equivalent list of the links"? Stevage 13:26, 11 March 2007 (UTC)

Single Area / clickable image
It would be nice if you could make clickable images easily by just giving the default area. Now you have to specify also a dummy rect area. And the default does not seem to work (bug?)

Can do!
I believe that we could enable clickable images simply by removing the test that requires at least one area to be defined. Ie. in, remove these lines starting about line 190:

if ( $output == '' ) { return self::error( 'imagemap_no_areas' ); }

This works for me, at least on MW 1.9.3:

I think this would be useful, and I can't see any harm. JohanTheGhost 19:49, 4 April 2007 (UTC)
 * This is in the latest release of ImageMap. BTW - the above patch is not "safe" as it prevents a check on no imput at all!  The fixed version has a safer check. Michael Daly 05:54, 5 May 2007 (UTC)

Extension extension
Hi Tim. Great extension!

I have a question:
 * Is it possible for a mapped area to trigger "Lupin's popups" like the unmapped area does? Or is that a question for Lupin?

And 2 really cool additions that should excite and intrigue you :->
 * 1) add a color-key (or similar) to individual areas. (Ambitiously with a "legend".)


 * 2) add an optional "detail" field to ImageMap such that a sub map will be displayed. E.g. for a detailed "ImageMap:Countries of the world allow a grab of (x1,y1, x2,y2) to display just an ImageMap-ed detail of central Africa.  (Even if the sub-map has to be created as a seperate image, allows the use of the larger ImageMap coords.)

Think of the possibilities! A single, really detailed map of the world/motherboard/whatever that can/would be populated as needed and grabbed willy-nilly the next time someone needs a submap. Now, a sub-map has to be re-ImageMap-ed all over again.

Don't those sound like fun???? --Saintrain 02:40, 2 April 2007 (UTC)

Other formats than JPEG?
I noticed that png-images are not working as image-source. Could this be changed?


 * This extension works just fine with png, gif and jpg. Perhaps your problem is that your installation does not premit png.  In DefaultSettings.php, you have the valid uploadable file extensions with


 * $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg');


 * If png isn't in there, copy the line into LocalSettings.php and change it to include png. Michael Daly 16:25, 13 May 2007 (UTC)

Enhance extension/fix bug

But linking to section within internal page does not work. Instead of arriving to someSection you arrive to the top of the internalPage:

Code fix
Look in Imagemap_body.php and find a line of code that looks like:

$attribs['href']  = $title->escapeLocalURL;

and change it to add the following end.:

Addition request: blue info icon only for logged in users
Hey this is sort of a request, would there be a way to make this extension only show the blue icons for users that are logged in? I'm using this extension to make images linkable to articles, and the wiki it's self is being used as a website/CMS. by hiding the links from guests that would allow the admins an easier time maintaining the image without having to go to image list, and keep the site clean for normal users. I tried to do this on my own but I didn't get it to work. Thanks.

"default none" would be useful
I would like to have an image that does not have any target link - purely acting as an icon. However, the extension complains when there are no links. -- Barrylb 02:01, 20 August 2007 (UTC)
 * Why would you use imagemap at all in that circumstance? If you don't want a link, just display the image alone.  Or do you mean that you want to use it as a means of turning off the link to the image page itself? Michael Daly 19:16, 22 August 2007 (UTC)
 * Yes, I would like to use it to turn off the link to the image page. Seems like a useful thing to do with extension. Barrylb 04:54, 23 August 2007 (UTC)
 * I'd expect some resistance to allowing that in this extension, since it's used in Wikipedia and they won't want to turn off the link to the attribution and copyright info for the image. You could try putting in a request via Mediazilla and see what happens.  I could see making it a site-configurable option - i.e. the wiki's admin can allow or disallow the use of such an option. Michael Daly 05:00, 28 August 2007 (UTC)
 * Though the blue icon is still there, and I don't know how to get rid of it, you should be able to just use it like this.
 * desc none</tt> does the trick :-) --Raymond 06:13, 29 August 2007 (UTC)

HTML image map extension. Not quite complete, but usable as it is.
 * What part of that is an error? It looks like a dump of the SVN info.
 * Did you download the files properly? I've seen something like this when someone thought they were downloading the file, but ended up saving the display of the SVN page instead.  When included into the LocalSettings.php file, it just spewed out onto the main page.
 * Look at the files you've downloaded with a simple editor and compare the content with the (view) of the same file from SVN. If they don't match, you've not got the proper PHP source. Michael Daly 15:49, 22 September 2007 (UTC)

Default link doesn't work
Clicking on an area with no link defined does not work in IE6 (will test Firefox later). Ironically, right-clicking and selecting 'open link in new window' does work. Also, the default link does work when no other areas are defined. Edokter 10:36, 2 October 2007 (UTC)

With circe:

Without circle:

Anchors on same page (create error on specialpage "wanted pages")
If I use an anchorlink in an imagemap that links directly to the same page (e.g. #foo) I get an errormessage on "wanted pages":

Fatal error: Call to a member function getPrefixedUrl on a non-object in /var/www/xyz/html/wiki/includes/SpecialWantedpages.php on line 105

This can be avoided by typing the full pagename in front of the anchorlink (pagename#foo). 84.57.191.5 17:53, 6 October 2007 (UTC)

Alt info?
How about adding Alt descriptions for those visually impaired folks who have to use special tools to get around the web? Is it implemented already? Because it is not demonstrated on the extension's page, and Dreamweaver keeps yelling at me to fill it :-) --Nathanael Bar-Aur L. 00:30, 23 November 2007 (UTC)


 * Check the page output source in your browser. You should see the alt filled in.  If you look at the image properties (in Firefox at least) you'll see the alt filled out.  Alt is filled with the text that follows the pipe in:
 * image:foo.jpg|this is alt text

--Michael Daly 07:11, 23 November 2007 (UTC)


 * I know, I meant to the setting of the Alt for each clickable area (poly, circle etc).
 * This is the html code Dreamweaver puts out:

<map name="Map" id="Map"> <area shape="rect" coords="71,17,101,43" href="http://www.somesite.com" alt="OPTION ONE" /> <area shape="circle" coords="64,80,10" href="http://www.someothersite.com" alt="OPTION TWO" />
 * I guess the program reads them out aloud one by one, so that the person can make a selection. Thanks, --Nathanael Bar-Aur L. 21:04, 25 November 2007 (UTC)

Blank page when called. (RESOLVED)
I'm not sure whats going on but when image map is enabled and an image map is put into the page the screen blanks on both preview and saved view. Running FC5, Apache 2.0, php5 fresh install of MW 1.11. I thought installing Wiki for a testing ground was going to be an easy install but I guess I was wrong.

commons images?
I noticed a problem when attempting to use an image from a commons-style repository:

uncyclopedia:fi:Malline:Lahjoitukset was showing "invalid or missing image" when the image itself was in a shared repository.

Once I download the image and upload it to that local wiki (uncyclopedia:fi:Kuva:Donation_button_fi.png) the problems go away.

Is this a bug, or just a case of trying to get the extension to do something it wasn't designed to do? --66.102.80.212 04:35, 1 January 2008 (UTC)
 * To my knowledge, uncyclopedia does not use the commons repository. <font face="Verdana,Arial,Helvetica"> Mønobi 06:05, 1 January 2008 (UTC)
 * The version for Finland uses a commons repository, just not "the" commons repository used by Wikimedia. --66.102.80.212 23:30, 21 February 2008 (UTC)

Bug in RTL mediawikis?
For some reason it adds a redundant horizontal scrollbar to the page on IE 7. See http://www.astropedia.co.il

Thanks, --Nathanael Bar-Aur L. 18:41, 16 January 2008 (UTC)


 * Comparing the IE7 and Firefox views of the page, I think the problem is in the CSS for the page rather than directly due to the imagemap extension (though imagemap may be exacerbating the existing problem). That's an educated guess rather than anything else, but I noticed that resizing the font ( <+> or <->) works fine in FF but is messed up in IE7.  In FF, the sidebar on the right is sized according to the font and the content area moves slightly to accommodate.  IE7, on the other hand, either has the content area overlapping the sidebar or moves the content far to the left.

it's possible to put 2 or more imagemaps in line? if yes, how? ( i prefer to not use a table. )
 * IE is picky about sizing of various objects on the page (especially s,

I know that i can use a table, i wrote that i prefer to not use it ;) maybe someone can add a code in imagemap to make it stay in the same line. I hate tables! ( and notice that they go in the next line, they cannot stay in the same line of the text )

This is not good, ex: i want to put two small imagemaps in text like "... text O text O text ..." Arlas!! 13:44, 2 mar 2008


 * Imagemap can't currently do this, as it wraps the image in a  of unspecified width.  This causes other problems.  There's a bug report on it.  A fix has been proposed and code for the fix submitted (by yours truly in mid 2007) but it has not been reviewed and acted on.


 * In the meanwhile, your only alternative is a table or to wrap the imagemap in a  of fixed width. --Michael Daly 17:11, 15 March 2008 (UTC)


 * I've had no problems doing this with a fixed-width wrapper and CSS Float. Works like a charm. Arodicus


 * Has there been any resolution to this bug? I haven't been able to get this to work in any reasonable way unless it's on its own line. Then I can float the imagemap or the text, but even with everything or just the imagemap within a fixed-width div, it won't stay on the same line as other text. - 24.234.156.46 23:17, 13 January 2009 (UTC)


 * This was supposedly fixed recently. I haven't updated to the recent version so I can't test it right now.  --Michael Daly2 03:58, 14 January 2009 (UTC)

Imagemap with the Imagemap Template from Wikipedia
Hello, I tried to use the Wikipedia-Template Template:Imagemap, but nothing happened. I want to use it in an other Template with some Coords, but it doesnt works. The output is just: ">Otzberg Can you help me??

&lt;div style="position: relative">
What purpose does the extra div serve apart from to restrict the possibility of using this for inline images? Is it possible to get a class-name added to the div instead of just manually coding in the style, both to be neater and also to allow for customisation? Conrad.Irwin 19:26, 7 June 2008 (UTC)

Add usual wiki picture border to imagemap pictures
I removed this from the feature requests, since it is already there. Imagemap can take all the parameters of an image. For example,


 * image:example.jpg|frame|center|300px|Bunch of text

will produce a frame around the image, the image will be centered on the page and 300px wide with the text as a caption. --Michael Daly2 04:59, 6 July 2008 (UTC)

Using Media Links

Javascript as part of Imagemap
Hi,

thanks for this nice extension. i have a map with some javascript elements, like onMouseover="ddrivetip('<img src=\'images/image.jpg\' />')"; onMouseout="hideddrivetip" />

the JS is for popping up some other image on mouseover. How can I make this possible?

is there any other way for this?

Creating a image dictionary
I believe that the imagemap extension could be nice to create a collaborative image dictionary like http://www.bildwoerterbuch.com (but better). We have enought pictures an interwikilinks to create such a thing where poeple have a way to learn languages. It would be a project between Commons, Wikipedia, Wiktionary and Wikiversity. I would see the meta files in the image description page at Commons and a translation tool at toolserver where the user could choose one or two languages. We would need a complete Interwikilink database and a tool like this from dapete to create such content. And it would be nice to see directly the vocabulary at screen, but this should be no problem for the script with the help of CCS, see. What do think about it? Interested? Where is a better place to discuse? --Kolossos 10:13, 21 January 2009 (UTC)

Imagemap and external images

Is there any way to use imagemap with external pictures ? Like

Test installation:

Text labels in image
Hi. I recently stumbled over an IMHO very ugly hack for creating image maps with text lables. For example one template using this hack is en:Template:Star_nav (and its translations in other Wikipedias). How about adding directly visible text labels (both: links and plain text) to the imagemap extension? It would very helpful as we could avoid a lot of multiple translated versions of diagrams (if you look at Wikimedia Commons you will find a lot of localised versions of diagrams) and of course yet another ugly hack could be avoided. ;-) Arnomane 21:55, 13 June 2009 (UTC)


 * A better solution would be to use SVG images with multiple language support. We're still waiting for full SVG support in browsers.  If you put multiple languages into the SVG image itself, essentially no change is required in this extension.  We'll have to wait for this SVG support, though. --Michael Daly2 18:16, 14 June 2009 (UTC)
 * Text labels would be very useful but I don't think it's realistic to hope for a SVG version of most images. Wouldn't that mean changing a huge number of images? 83.134.216.150 22:37, 30 June 2010 (UTC)

Additional rationale
On the English Wikipedia, there is an image of a carburettor labelled with English text. The same image is used on several non-English Wikipedias,, , , ,. In each case, these non-English pages have an image with English labels, not exactly ideal. So should there be copies of this image with text modified for each different language? That would be quite laborious and result in many duplicate images.

And this happens repeatedly: a quick search shows, , ,...

Having text labels handled by imagemap would allow the labels to be handled/translated separately from the image. It might also help along the development of a Wikimedia visual dictionary/picture dictionary project. 83.134.216.150 22:37, 30 June 2010 (UTC)

Problems with in links
Hi. Thanks for the great extension! However, I have a problem. I have the following:

But it says "Error: no valid link was found at the end of line 3". So I read this page and then tried:

But that throws the error "Error: at least one area specification must be given". I tried adding a rect etc, but it still throws the error. Any ideas? Many thanks! [User:Mitchelln|Mitchelln]] 11:43, 18 June 2009 (UTC)

Mark the selectable arrea
Feature requests : It would be nice if the area which is clickable can be displayed with f.e. dotted line. Then the user knows, without the need of moving the mouse, which area is selectable. This is especialy usefull for small area's and for area's which are hard to gues it is (or it might be) selectable. It would be perfect if the line type and colour can be set different for each link. Each link type can have its own colour so the user knows what to expect. Imagemap is a very nice extension which I use a lot. --BernardHulsman 15:46, 24 June 2009 (UTC)

Testing and Suggestion
Can you make a syntax element for background bgcolor (templates)...etc above="" below="" Note: if the image is GIF don't define it, if you really want a background color try developing a method for Gradient syntax.
 * transparent
 * white
 * autodetect (if the image doesn't have a border e.g. autodetct the background components color. e.g. if use it in article (background is article space),
 * color;RGB (enter RGB color or Hexadecimal colors)
 * color;CMYK (enter RGB color or Hexadecimal colors)

No Border Test --75.154.186.241 01:15, 29 June 2009 (UTC)


 * Imagemap just provides whatever is available from the image link extended syntax, so if you want anything changed in that regard, you should go to MW's bugzilla and put in a request for the image link syntax to be extended further. --Michael Daly2 17:34, 29 June 2009 (UTC)

Alt text
Yes, there is a section above that discusses this, but it seems to have been lost amongst the shuffle and I think this is something that needs to be fixed so imagemaps can be used more readily.

Currently image maps will insert the name of the article being linked to/the piped entry for the article into the alt parameter, the same as it puts into the title parameter. Is it, or can it be made possible, to set a custom alt text that is different from the text that will show up to users when they hover their mouse over the link? - Floydian 19:10, 27 October 2009 (UTC)

extension simply doesn't work.
mediawiki 1.11.2

php 5.2.6

mysql 5.0.67

imagemap installed per instructions. shows up in Special:Version

double checked that imagemagick was installed and in use. LocalSettings.php confirms both.

double checked that php DOM was installed. phptest script confirms.

wiki markup:

it is what is seen below, with a few carriage returns.

what i get on the page:

Filepath function does not work
Problably an stupid mistake from my side but the absolute path reference is not working

The first link is only jumping to the internal WIKI page containing the downloaded mp3 file The second external link is ok

What we wanted is simple an clickable sound array from an image Note: This creates an nice direct url link to the file without maintanance in case the file name etc changes therefore we need an direct relation to the above file otherwise you could use [http:// www.xxx.com/wiki/blablabla ]
 * Step 1: upload an mp3 file eg Food_ch.mp3
 * Step 2: Test the access to the Media (music) file  [] 
 * Step 3: insert this link to the above example

This produces an unexpected error Error: no valid link was found at the end of line 3

any good suggestions to recover from this error?
 * Actually it's the same on my wiki, the line 3 error comes from the accolades, and without the accolades no clicking sound is possible... JackPotte 07:42, 21 August 2010 (UTC)
