PaperLuigi already stated it WASN'T a contest, bobman.
Anyway, I know I'd get very annoyed within a week of only image posting. I mean, the forum doesn't allow images in sigs or avatars (in the "main" skin, anyway) for a reason, so unnecessary/irritating images wouldn't clutter the pages.
Though you're not breaking any rules, I do believe you are crossing some sort of line with this certain challenge.
