Winows only: If you've checked out some of our suggested wallpaper resources, you've probably amassed quite a collection of swanky desktop wallpaper. Keep things in a fresh rotation with Wallpapa a lightweight wallpaper switcher.

Chewing up barely 2MB of system memory and hard disk space, Wallpapa is all-around lightweight. You can add multiple directories and their subdirectories to Wallpapa. Background changes occur manually, on system start, or on a user-specified time interval.

Wallpapa supports BMP, JPG, PNG, and GIF and you can set it to scale, crop, or tile background images automatically. For another excellent wallpaper switching tool, make sure to check out previously reviewed Caledos and Display Fusion for multiple-monitor setups.
