I've written a little tool [1] that shows file duplicates between a wikipedia and Commons, as well as internal duplicates. It runs of a static list created from the toolserver databases; currently, German and English are available. I will have to regenerate the data for other wikipedias and for updates manually. But for now, there's ~29.000 dupes between en.wp and Commons, as well as ~8.500 between de.wp and Commons, so it might take you guys a while ;-) A subset (default:25) images is selected randomly from the list, so you might run into images that already have {{NowCommons}}.

A usage count for the images would also be nice :) And last but not least: Buttons that generate a preview with {{NowCommons}} directly under the image ... Sorry to bother you and thanks for this great tool.

I wrote http://toolserver.org/~multichill/nowcommons.php a while ago, less colorful, but should work on every wikipedia.

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.
