I could see adding an {{information incomplete}} (do we have one
already?) to images that meet our minimum requirements to stay on
commons, but are lacking details - often images are uploaded from some
other site, people not realizing that there is a definitive source with
more information.
    

That's a good idea! At least then if a gallery says "But you don't
have complete information" we can say "There's the 'so fix it' tag,
your information would be most welcome and will be added."
