I dont mean to sound a dick here, but you can hardly complain if a image was accepted by a database user, when you yourself didnt notice any issues originally and uploaded it to the database in the first place. Adding some information to the corrected image to reject the first one wont work either as the person accepting the original image likely wont of seen the second one with the message, so accepted it. A image with a small issue is better than no image at all at the end of the day.
Submissions to the database need to be scrutinised by not only the moderators, but also the original uploader, as everyone involved in the process is human so oversights and mistakes can and will happen from time to time.
