ScrollWall
can be modified whenever you want.
With the use of a very basic tool called ScrollWall, you can programme your desktop wallpaper to change automatically every set number of seconds, minutes, or hours. Another option is to have it switch the desktop background each time it boots up. You may choose the wallpaper set from your computer, and you can change it whenever you'd like.
The thumbnail view it offers for the chosen wallpapers and the one-click wallpaper changing capability set it apart from other programmes in its category. IE allows you to quickly switch your desktop wallpaper by just clicking on the tray icon.
