Karsten SlideShow is a playlist-based slide show program for picture and movie files on Windows. It offers flexible, item-related control over the presentation sequence, and runs shows in a window, the screen saver, or the desktop wallpaper.
easy to use diashow for pictures & videos, but no alphabetical play-sequence.
Pros: Quick and easy install. Intuitive GUI. Lightweight. Cons: Needs some options for how images are oriented or sized. Several of my high res photos only show a small corner as all images show at their full size. Best active slideshow app I've found on srouceforge.
