So that error is still around? Figured they'd have fixed it by now, though of course I'm rather out of touch with the situation, as I don't use Photobucket myself.
At any rate, I have to stress the importance of backups once more - don't delete your dolls, or anything else you've uploaded to the internet, from your computer if you want to make sure you'll be able to use them again in the future.
If Photobucket is giving you trouble, maybe try an alternative image host, such as
TinyPic or
ImageShack.
