Or run the following: find ./ -iname "*" -type f -exec file {} \; > /tmp/file.txt from inside the Wallpaper-folder and check the output (see file /tmp/file.txt) for anything obvious. You will have a long line per file, so using "grep -v " to filter out known good results might help in finding the problem file(s) -- Joost
