Sure ill provide some kind of link to you im a PM the next time it does it to me. The only workaround ive found so far is to delet the image from "My Pictures", go into my graphics program, make some slight change, resave the file, and then re-upload until it works.
Im thinking maybe changing the image and resaving in my graphics program probably doesnt do anything, its likely just that after removing from "My Pictures" and re-uploading over and over, eventually it uploads correctly.
