I put a pic as a wallpaper for one the desktops and now it won't change to anything else. Now matter what theme I use, or what image set I use, all the wallpapers change except the one on that desktop. I've edited the .desktop file and it still does not work. It changes the wallpaper for all the desktops but not that one. Does anyone know where the background image is located? Maybe I can delete that file...?? Ive tried rebooting the phone

EDIT: I've tried changing it from the desktop settings, and from the photo manager. Neither works.
