ScreenThemes is a wallpaper changer and a screen saver that displays stunning, full-screen digital photographic images. The wallpaper changer can randomly display new images at different times. There is an option to make the text of your desktop icons transparent. You can also superimpose a monthly calendar over your wallpaper. The screen saver displays the images in a slide-show style. You can select the time delay and use transition effects between images. You can even listen to WAV, MIDI and MP3 music while watching the screen saver. There is a "surface texture&quot\; option which makes your images look like they've been painted on canvas, wood grain, crumpled paper, or cracked marble. ScreenThemes automatically sizes each image to precisely your screen resolution, from 640x480 up to 1280x1024. It includes high-resolution photos taken by professional photographers. ScreenThemes also lets you crop, stretch, rotate, flip and edge trim your own JPG photos and set them as your wallpaper.
