WimpWall is a free, easy-to-use and highly flexible wallpaper exchanger. The program automatically starts with Windows and chooses random images of wallpapers stored in the folder you choose for it. You can choose more than one folder, if you want.
WimpWall places the image in the center, and if necessary to improve the visualization, stretch it to fit better. It does not require any other program: it has autonomy on its own. Work with JPEG and BMP images. Remember, yes, the images must be in folders. WimpWall does not work with single images. If it bores you to always see the same wallpaper, WimpWall is your program.
You can free download WimpWall 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
