I don't know about Greg, but I certainly can:

As of last March, approximately 2000 images were uploaded to the
English Wikipedia each day.  Of those, roughly 50% had clearly
incorrect license information.  Of the images claimed as "fair use",
roughly 35% of the claims were immediately obvious as being invalid.
I haven't seen any sign of the ratios changing since then.

Based on a random sampling of 50 talk pages of users uploading images
without source information or license information, 80% of these users
have no talkpage traffic other than notices about image problems, and
maybe a welcome message.
