Quicktime works fine for still image slideshows. Liveslideshow generates Quicktime movies, and there is some capability built into the latest Quicktime Pro for still shows. You don't need a frame rate of 29 fps to display stills. You can get by with as few as 7 fps, even with the transitions. Also, not all of those frames need to be key frames, and if you have a decent codec, the bitrate is not that bad. I've done some slideshows in Flash movies with a very low frame rate, and it was fine. The size of the movie was smaller than my PTE executables, but the problem I had with Flash was that the audio wasn't smooth (Flash just isn't designed for it). I've only been trying the demo version of Liveslideshow, which only allows 5 images, but for those 5 images (approx 800x600 not highly compressed), running nearly a minute, with transitions, the size of the QT movie was only 517kbytes (no audio added yet). And it looks fine.
