Some possible reasons: 1. Someone posted a very nasty, trollish comment on their image. Faster (maybe even easier) than getting a Mod or Admin to fix the problem for them. 2. They get little or no response. As an experiment, they repost it later to see if the posting day or time was a factor. 3. Maybe they made a small change that is not at once obvious to the viewer. (Forgot the signature, wrong year, wanted to change the eye color, different thumbnail).

This is not my "second childhood". I'm not finished with the first one yet.
