I'm glad you solved your problem. I've been having the same one and I don't seem able to get it licked. Tried changing all my thumbs to "...thumb.jpg. It didn't work. As for updating my browser, I've got IE 6.0.2900.etc, etc. The only way I can get my stuff up is to upload everything but the thumbnail, then go back to "edit" and then upload the thumb. If anybody can figure out why or has some tips, I'd be glad to hear them. Thanks.
