Hey pharaoh ! how ya doing?
you can use almost any pic you have on your hard drive, what ever program you use for virewing pic's .jpg, ,bmp or whatever should have an option to " set picture as wall paper"
if it don't fill up your screen you can streatch it fo fit, by right clicking a empty space on your desk top then click properties, when the box opens you should see options for streatching, centering, and tile.
I got my wallpaper right from here techimo, and photoshopped it, so my nickname is showing.
