Ugh, this is why I'll never use photobucket. It never seemed stable for hotlinking anyway with all the constant changing and upgrading. Too often I see pictures on forums that weren't posted long ago with the "sorry, this image is blahblahblah" message instead of the image.
I don't host galleries anyway, so if I want to post a pic I'll use imgur, tinypic, imgbox or DWteam. If I absolutely need to post several images at once, I use imagebam's gallery feature. The only downside of imagebam is you can't sneak around the thumbnail coding to link the fullsize pics or you get a broken picture icon. (I do at least :P)
