PhotoFlash uses Windows' Active Desktop feature to add a slide show to your wallpaper. Use pictures from any source-a digital camera, a scanner, even the Web. PhotoFlash creates HTML wallpaper that displays your favorite photos without obscuring your icons or work. The wizard-style interface lets you control the size, placement, and speed of your slide show. Place the slide show at one corner of your desktop or size it full screen. PhotoFlash displays photos on top of any wallpaper or background. Photos change at whatever interval you specify. The wizard-style interface guides you through the entire process.
