This program sits in your system tray area and allows you to choose a directory of images you want to use as wallpapers, and Wallpap1 will automatically update your wallpaper using the images in the directory you specify and at the cycle/interval you specify. It supports GIF, JPG, PNG, and BMP. You can also set it to minimize/start on start-up and rotate them randomly. You can right-click on the tray icon for the basic options. No dll's or OCX's needed! Wallpap1 is donationware -> if you use it and like it, please send me a postcard and/or a small donation. :)
