Hi all,
As you may know I have been working on GlobalUsage, a MediaWiki extension that allows showing on which Wikimedia wikis a Commons image is used. We had some problems before, requiring it to be disabled before deployment complete, but now it has finally be deployed and the data set has been built.
You can now view where an image is used on the bottom of the image description page, or via Special:GlobalUsage. [There is still a problem in the special page causing the "prev" link to not work, but the fix for that will be deployed soon hopefully]
Best regards, Bryan
