And, could this tool support other projects?
I wrote
http://toolserver.org/~multichill/nowcommons.php a while ago,
less colorful, but should work on every wikipedia.
Many other projects have copied PD images from en.wp,
and those images
have since been moved to Commons. It would be a great help to be able
to quickly go around the smaller projects and assist them to use the
images now on Commons, and remove the duplicates. I was just now
doing this over on en.wv, and was thinking that I need a tool to help
find the dups!
At the nl wikipedia i created a template a while back to mark images
moved from other wikipedia's, but not yet transfered to Commons. The
template makes the images end up in
http://nl.wikipedia.org/wiki/Categorie:Wikipedia:Afbeelding_afkomstig_van_e…
This can be very useful to mark images and later transfer the source
images to Commons.
