This patch causes Special:Unusedimages not to list images that have been put
into a category. This is usefull for the commons, where images don't have to be
on a article page, it's enough if they are categorized. For that reason, the
current behavior of Unusedimages is useless on the commons - it lists a lot of
images that are categorized and therefore do not require attention.
The patched Unusedimages still lists images that are categorized indirectly
through a template (this is due to the way the table categorylinks is build).
This is actually The Right Thing in most cases, as it causes images to be listed
which are only in copyright-categories. But it does lead to some false positives.
Note that it's safe for all wikis to apply this patch, as it has no effect
unless $wgCountCategorizedImagesAsUsed is set in LocalSettings.php; This patch
has been tested with MediaWiki 1.4.1 (CVS-Branch REL1_4), it does not use the
new database schema. Also note that unlike the current version of Unusedimages,
it queries the cur table - there my be performance issues with that, I don't know.
(hm, where do I add the patch? After I submitted the report I guess... we'll see)
Version: 1.4.x
