Create custom screensavers in minutes. Screensaver XP allows you to create and distribute professional screensavers for Windows systems. Selecting your favorite photos and sound files from your hard drive is an easy drag-and-drop process. You can preview your screensaver as you build it. Then with one click, a screensaver, equipped with an installation file, is created. Screensaver XP supports common image formats including GIF, JPEG, BMP, SWF, movie clips, and RealPlayer and MediaPlayer video formats. Additional customization features include the option to add music, preview slides, set a picture's height or width, choose background colors, turn sound on or off, display in full-screen, set the slide-transition time, and add text messages to slides. It supports unlimited image and sound files.
