So here is my problem. In iTunes, I can set up a smart playlist which constantly updates 8 hours of random music from my library, using "last played is not in the last 6 months" - this way I know I won't get any repeats too quickly. I would like to set up a smart album in iPhoto (or in the Finder, for that matter) that contains 200 random images from my iPhoto library, and switches them out after they are viewed. I have been searching for a way to do this for about a week now, with no success. Is this possible?
