photobucket does put your user name in there somewhere. i would recommend getting a different account (i think they are free anyway)
got this info from that tcho guy
qoute:
The url thing is the same subdomain (or whatever you call it) as an older account. So say you had a geocities account (substitute whatever it is you kids use these days) and you hosted images from there, it'd be a link. So say you used
www.geocities.com/mysite/image1.jpg from an earlier account and it got suspended. So you created a new account and you used
www.geocities.com/mysite/image2.jpg, well it's the same url just different pic, so you're screwed. But say you used
www.geocities.com/diffsite/image1.jpg, then that can't link you (although if the pics are the same that's a different proof in itself).
