Slideshow in MediaWiki

 * MediaWiki version: 1.13.3
 * PHP version: 5.2.6-5 (apache2handler)
 * MySQL version: 5.0.32-Debian_7etch6-log
 * URL: http://rafnem.hi.is/hiwiki/index.php/Main_Page

I am getting acquainted with MediaWiki in connection with a school information project. This is very promising and started me thinking of a wider application: Would it be possible to use MediaWiki for a photogallery, with thumbnails and slide show for all photos belonging to different categories?


 * 1) I have a collection of photos, say for the years 1942-1972.
 * 2) I put one photo in each article in the wiki, describing what is taking place, and categorizing it, by year, by name of the people seen in the photo and any other imaginable feature.
 * 3) If I after this choose the category "1957" all photos belonging to that category should be presented in a thumbnail gallery with the option of a slideshow and all or part of the description. If I choose the category "Vehicle" all photos in that category would be presented, ordered by year.

The same goes for many pictures in a single article. Even using the tag I can't see an easy way to move between the pictures, I have to back out of each one and drill down to the next.

Error creating thumbnail: convert.exe: unable to open image :Permission denied @ blob.c/OpenBlob/2439

 * MediaWiki version: 1.14

Been battling this for a few days now, it's been one thing after another. This is on Windows and IIS, as indicated by the error message. I seem to have run out of options I can think of/find. Any help would be appreciated.

Hi Chris, I am no expert but I have encountered this problem before. Are you on shared hosting? If so, your webhost may not be allowing ImageMagick. Two of my webhosts use GD instead, in which case, you just need to set $wgUseImageMagick = false; and it will work fine. &mdash; PM Poon 17:26, 1 May 2009 (UTC)

$wgUseSharedUploads

 * MediaWiki version: 1.14.0
 * PHP version:  5.2.8
 * MySQL version: 5.0.77-community
 * URL: http://aseanpedia.com

Hi, I am operating multiple wikis and I think the use of $wgUseSharedUploads is a good idea. However, the instructions at Manual:$wgUseSharedUploads assume some background knowledge and are incomprehensible for a novice like me:

If you operate multiple wikis, you can define a shared upload path using $wgSharedUploadPath. If $wgUseSharedUploads is set, the wiki will look in the shared repository if no file of the given name is found in the local repository (for, [[Media:..]] links).

Thumbnails will also be looked for and generated in this directory.

Uploads to the wiki will NOT be put there - they will be put into $wgUploadDirectory.

Supposing I create a new wiki called imagewiki.com and a database called Imagedb:
 * How should I tweak my LocalSettings.php? Do I need to tweak both the LocalSettings.php for aseanpedia.com and also for imagewiki.com?
 * Can I use a "false" (unregistered) domain name? &mdash; PM Poon 17:21, 1 May 2009 (UTC)

Thumbs are not centered
Look here Help:Images and scroll down to "Thumbs". The picture and the text is not centered within the lighter area arround it. --Lastwebpage 20:05, 7 May 2009 (UTC)

Error creating thumbnail

 * MediaWiki version: 1.14.0
 * PHP version: 5.2.0-8+etch15
 * MySQL version: 5.0.32-Debian_7etch10-log

After upgrading from Mediawiki 1.13 to 1.14, I have an "Error creating thumbnail:" without any further information. I use ImageMagick 6.2.4. My local settings are: $wgUseImageMagick = true; $wgUseImageResize = true; $wgImageMagickConvertCommand ='/usr/bin/convert';
