Just a suggestion...I also post on a couple of other art websites and one allows people to upload minor revisions of images without having to start from scratch with votes and comments. Of course major revisions require a new upload. The way it's done is that the artist uploads the revision and it is reviewed by site administrators. If the revision doesn't alter the image significantly, the older version is simply replaced by the newer version. Otherwise, the artist is directed to upload the revision as a new image. I know I've often uploaded two or three versions of the same image because of some small changes and wish I could have run it by moderators here for permission to switch images. ... Wen
