Thanks for this great extension! I can't get the tag version to work, but the parser function is moving along.

I have a question about slideshow.js. Should line 30 say:

Documentation
Great Extension... mostly. -Random User 8:08, 28 October 2008 (PST)
 * parser function works, tag call doesn't, can't find documentation as to how / why.
 * multiple calls of the parser function in a page do not seem to function; would love to know how to fix this.

Header warning
Trying with 1.13.2 and always get a warning: Warning: Cannot modify header information - headers already sent by (output started at /usr/local/apache2/htdocs/wiki/extensions/Slideshow/slideshow.php:146) in /usr/local/apache2/htdocs/wiki/includes/WebResponse.php on line 10 the include_once statement is right after <?php in LocalSettings.php. Am I missing something ?

Transition problems
The transition "cut" is working, fade and blinddown are not. What could be the reason? -- Tom B. 10:21, 21 January 2009 (UTC)

Location for support
Actually, is this the right place for questions anyway? -- Tom B. 10:21, 21 January 2009 (UTC)

Warning: Cannot modify header information etc.
As good place as any to ask, the extension definitely ain't working. I get exactly the same errors, testing on a fresh installation of MediaWiki 1.13.3. After all, in the blue box on the main page of this extension it currently says it has been tested on 1.11.0.

 * Remove the ?> from slideshow.php. —Emufarmers(T 18:05, 7 February 2009 (UTC)

Key presses between frames

 * I think this is a great extension for displaying images with nice transitions.
 * But I look for a slideshow extension which continues with the next frame when I press a key
 * Maybe this could be considered in the future

Can I use this extension with 1.15.x?
My friend said that he can't install it on his 1.15.1? How will i install it? Chernobyl 13:21, 17 November 2009 (UTC)
 * Works for me on 1.15.1. To use other transtions other than cut, don't forget to download and copy the mentioned .js files. Everything need to know is ont the extensions page.--213.134.24.64 00:33, 19 November 2009 (UTC)
 * it works on 1.16 too. Adamtheclown 03:12, 14 December 2010 (UTC)

Incompatible with XML compatible skin ?
Hello, thanks for the extension. I successfully installed this extension in Mediawiki 1.15.1. However, when I changed my skin to XML-compatible one (as required by Extension:ASCIIMath4Wiki), this does not work anymore. All images were showed, instead of one slide at a time.

I cant' align my slideshow
I want my slideshow appear center on my homepage. I have this:

 * The hack I've done is  - Andreslucena 13:57, 1 June 2010 (UTC)
 * Unfortunately this does not work for me. The slideshow still shows on the left. I tried putting it in a table, but it ignores the align=center :(
 * Mitchelln 10:29, 14 October 2010 (UTC)

With MediaWiki 1.15.1 this works, using either format described by the author. HOWEVER, I too observe the trouble that the positioning if the display is not quite right. Text can't flow around the image, and the image resists any re-positioning. I gather the author did that to work around some flaw in Microsoft IE, but I wish there were some option. I really need to fit the image in "tightly" with words around it on the sides.

Could the author provide a little advice on this? Pauljohn32 06:05, 7 December 2010 (UTC)
 * same problem. and table does not work. Adamtheclown 05:39, 14 December 2010 (UTC)

Will not work if your wiki is in the root folder

In 1.15.5 using Javascript Slideshow is strange, if I type:

 * the problem was my wiki was in the root folder, instead of in /w/ or /wiki/ once this was fixed, there was no problem. See Template:Wiki-in-docroot Thanks User:Emufarmers for this help!

1.16?
Doesn't seem to work in 1.16. The simplest tick/tock code from above just shows both "Tick" and "Tock" as static text and based div doesn't show up at all.
 * I am using 1.16, and the tick tock works and the  tags work. this does not work though:

Adamtheclown 20:14, 13 January 2011 (UTC)


 * The above code doesn't work as you need to enclose each element you want to rotate in a  tag. Njw (talk) 17:58, 18 February 2013 (UTC)

Cannot modify header error for me too
I too get the error when I try to add this to my site. I searched slideshow.php for the "?>", but it's not there. Any ideas why it doesn't work?

MediaWiki	1.14.0 PHP	5.2.14 (cgi-fcgi) MySQL	5.0.91-log

This is the error I get: "Warning: Cannot modify header information - headers already sent by (output started at /home/content/w/a/t/watc/html/extensions/Slideshow/slideshow.php:7) in /home/content/w/a/t/watc/html/includes/WebResponse.php on line 16"

Wow, I feel like an idiot. Got it figured out. I right-clicked and saved the php and js file instead of clicking the link and copy/pasting the text. Geez...duh!

Is it possible to redirect image clicks?
I was just wondering if there is a way to redirect the clicks on the pictures? Right now if you click on the image, it takes you to that image's page. In my case, it would be nice if it would actually direct you to the page that image is being used on.


 * You can use the link= parameter. —Emufarmers(T 05:43, 21 January 2011 (UTC)


 * Thanks, but I can't seem to get it to work. It just directs to the image itself and not the page.  This is what I have in there:

--Ned4spd8874 04:00, 24 January 2011 (UTC)


 * link= doesn't work with the thumb parameter before MediaWiki 1.17. —Emufarmers(T 04:07, 24 January 2011 (UTC)


 * Crap! --Ned4spd8874 16:52, 24 January 2011 (UTC)

Javascript Syntax Error
I'm getting a syntax error that is keeping the slideshow from displaying properly. When viewing the source, I see this:



/*<![CDATA[*/

startSlideshow('blah', 1000, 'forward', 'cut');

/*]]>*/

Of course HTML tags should not be in the script syntax, but I can't figure out what is causing them to be placed there. What am I missing? By the way, Tidy is not installed as an extension.


 * I'm made change in slideshow.php:

$script = << /*<![CDATA[*/ startSlideshow('$id', $refresh, '$sequence', '$transition'); /*]]>*/ ENDSCRIPT; to $script .= "/*<![CDATA[*/ startSlideshow('$id', $refresh, '$sequence', '$transition');/*]]>*/ ";
 * After that this problem was solved. --Vpovilaitis 09:20, 26 January 2012 (UTC)

Serius bug re. maxWidth
Hi.

I noticed that when using image sizes, the slideshow has a much larger width than the specified image size. For example I have some 1024x768 images which I reduce to 500px using:

However, the javascript picks up the original image size rather than 500px. So spacer.style.width = maxWidth + 'px' is set to 768px rather than the specified 500px. The result is massive space to the right of the slideshow.

Could the code be modified to pick up the image size that is being passed in?

Thanks! --Mitchelln 14:16, 11 July 2011 (UTC)


 * This doesn't seem to be an issue with current versions of the code; I can't reproduce it. Let us know if it's still an issue. Njw (talk) 17:51, 18 February 2013 (UTC)

MediaWiki 1.17.0 and the Fade Transition
I have tried everything, spending hours, but cannot get the fade transition to work on my website (or blindDown), although cut works great http://wheretosee.org/wildlife/Main_Page -- see the Photo Gallery page. And yes, I have loaded the scriptacolous scripts (I even went back three revisions, in case a later revision was incompatible). My code is:

Is there any issue with MW1.17.0? Or an issue with later revisions of scriptacolous?

Internet Explorer 9
I am using this extension with Scriptaculous for fade transition. This works well on all browsers I have tried except for IE9. IE9 seems to ignore the delay between the slides and displays them almost simultaneously. Has anyone else noticed this?--Paulreed 14:24, 21 November 2011 (UTC)


 * Which method are you using - the tag or parser function? I think you have to use the parser function.
 * --Mitchelln 17:23, 7 February 2012 (UTC)


 * Note that since the extension has been rewritten to use jQuery rather than scriptaculous this is unlikely to still be an issue. Let us know if it is. Njw (talk) 17:44, 18 February 2013 (UTC)

Using more than one tag (fixed in v1.1)
Hi, when I'm using more than one  tags, the first   options are not working, and start behaving using the second or the latest ones if using more than two tags. In the previous version 0.2.1 (using MW 1.16) each tag worked as individuals. REX (talk) 03:35, 5 April 2012 (UTC)


 * That's my fault - I was aware of that problem when I redid the code, but I didn't know if anyone had more than one slideshow on a page. I'll try to fix that soon. Yaron Koren (talk) 13:39, 5 April 2012 (UTC)


 * Thanks a lot! :-) REX (talk) 13:50, 5 April 2012 (UTC)


 * I installed the 1.0 revision, but the Options/Attribute still troubled when using two or more tags. REX (talk) 02:26, 19 February 2013 (UTC)


 * The version number was not my idea :/ I would have give it 0.5. This is on the todo list. I'll take a look how to solve this. --DaSch (talk) 11:39, 19 February 2013 (UTC)


 * I fixed this, and it's now in git, and it should be in a v1.1 release soon. Note that this change requires $wgHtml5 to not be false to work. Njw (talk) 15:34, 21 February 2013 (UTC)

Install crashes wiki in 1.16.5
Hi. For some reason installing this extension on my wiki crashes the whole thing. I've created a 'Slideshow' directory in extensions and included the slideshow.php and slideshow.js files in the folder. As soon as I add the 'require_once' line of code to my LocalSettings file my whole wiki goes down.

I can't see any obvious solution to this. I running my wiki through MAMP and it's installed in the htdocs folder. I've had no problems with any other extensions. Any ideas? --Mqbpjdj2 (talk) 10:07, 18 May 2012 (UTC)

Any news for 1.19.1 ?
The examples are quite inviting and I would love to try this extension, but it crashes 1.19.1 at present - July 15 2012

thank you


 * It works fine on 1.19.2, so I suspect you just didn't install it properly. Let us know what the exact problem is if it's still an issue for you. User:Njw 10:01, 22 January 2013 (UTC)

Slideshow element is on top of text in Firefox and Chrome
When I insert the slideshow element on a page, it shows up in-line with the text on Internet Explorer, but on top of the surrounding text in both Firefox and Chrome. Upon closer inspection, it seems the problem is triggered whenever the images are given any options that cause them to be rendered as a floating block. Has anyone got any tips for how to correct rendering in all browsers? --143.97.2.35 09:07, 7 August 2012 (UTC)

License & code location
The extension page says "no license specified". I presume that means the code is GPLv2, as the rest of mediawiki, but it would be good if the authors could explicitly state this, so it can be more confidently used.

Also it would be reassuring if the code could be checked in to git sometime; code on the wiki feels somewhat scarier ;)

 * The author of this extension isn't active since years. So an answer can not be exacted. I'll put this into github. --DaSch (talk) 19:45, 25 January 2013 (UTC)

Doesn't work correctly in IE6/IE8 (fixed in v1.0.1)
This doesn't work quite correctly in IE6 or IE8. What happens is that the images are scaled to about 10px wide (despite being set as 790px in code), and on the transition they flash for a moment at 790px, then go back to being compressed.

A workaround for this is to manually set the div containing each slideshow image to the correct width (800px). Then everything works as it should. So I changed my code from this:



to this:



This is surely due to a bug somewhere in the expectations of IE, but I don't have the time to hunt it out, now that I have a workaround. -- User:Njw 17:50, 11 February 2013 (UTC)

Note that the extra CSS suggested in the Installation section also fixes this issue for me. As can be seen in the above examples, though, these aren't embedded images, but standard images uploaded to the wiki. So perhaps the CSS should be added by default by the extension? -- User:Njw 09:50, 15 February 2013 (UTC)

Actually on further testing the CSS mentioned doesn't fix the issue for IE8, though it does for IE6. -- User:Njw 10:00, 15 February 2013 (UTC)

I just checked and this bug still exists in the newly released v1.0. Njw (talk) 13:10, 17 February 2013 (UTC)


 * I think the CSS could be included within the extension and maybe it could be improved to work with all versions of IE? --DaSch (talk) 18:09, 17 February 2013 (UTC)


 * I fixed the problem, and DaSch kindly applied the patch, so this is fixed as of v1.0.1. Njw (talk) 17:40, 18 February 2013 (UTC)

Slideshow can't be centered
The slideshow can't easily be centered. (This is the same issue as mentioned above under "I cant' align my slideshow")

Enclosing the whole lot in a  tag doesn't work, nor does adding a   css rule, nor does adding   to included image attributes. I think this is because of the way the slideshow uses absolute positioning, and needs some thought on how to fix.

Extension does not show up images (fixed)
I installed the Slideshow-Extension to my MW 1.18.5, but images do not show up. If I reload a page, all images of the slideshow show up for about 0.5 seconds and they disappear.

Only if I reupload my localsettings.php the slideshow seems to work, but when I edit the page, i got the same problem as before. Here is one example-page: http://www.emrichmail.de/wiki/Materialerstellung:Hauptseite

Known issues with 1.19.4 or other extensions?
After installing, my wiki won't show up again. I had to comment the "require_once" tag out for the wiki to become available. I'd say I did everything correctly (isn't that hard to unpack, rename, upload and enter the tag in the LocalSettings.php.
