Paper Changer is a small application for changing the background wallpaper on the windows desktop from a random selection of JPEG images within a specified folder. Paper Changer can be set to change the wallpaper every time that you start Windows (without remaining loaded) or just used to change the wallpaper whenever you get bored of the current picture. Paper Changer stretches the image to fit as much of the desktop as possible without distorting it.....(free).....
