Re: [Gimp-user] Corrupted JPEG
Phil, I doubt that you can do much with these images other than extract the thumbnail which is obviously quite small. I used jpeg snoop (http://www.impulseadventure.com/photo/jpeg-snoop.html) to examine file number 4 and there are markers in the file that should not be there. Perhaps you can use a hex editor to fix it, I have no idea.
