I would like to have a collection of images displayed in random order as a slide show . Ideally these images could be in separate folders on one hard drive. In particular, I would like to hang a LCD screen on a wall and have a computuer send a random selection of images. Sort of a dynamic framed print. I know I can do this in Windows, if the files are jpegs and in the "My Pictures" folder, but would like to find a less restrictive program,i.e, one that would use all the images on a drive and is not limited to jpegs.
