This works perfectly for me OP, it's a program called:
BioniX Desktop Wallpaper Animator
It's free, and it watermarks the wallpapers in PNG or JPG, but not GIF for some thankful reason.
The gif wallpaper settings are up the top dropdown menus under
Tools > Wallpaper Animator
Have fun man, and thanks to /WG/ for all the awesome walls, you guys rock:)
