If you are looking for a bit of variety when it comes to your system’s desktop backgrounds, you have lots of choices. If you run Windows 7, you can simply install a theme with multiple wallpaper images. Alternatives are so called wallpaper changers that either pull wallpapers from local storage devices or the Internet. Some of the programs we covered in the past, are the desktop wallpaper changer Wally , Wallpapa or Wallperizer .
