I need to create a very simple slideshow, to play slides in a random order and the ability to play them anywhere from 1 minute each to 5 or 10 minutes each. I use it for figure quick sketch practice. It's something artists do a lot of, and I used to do it all the time with iPhoto and Aperture. I'm so disappointed that there's no way to play a slide for longer than 20 seconds, and can't understand why there even needs to be a limit. So then I tried the manual option, thinking I could just set a timer and advance the slide manually, but this way it plays the slides in order, which doesn't work at all for this purpose. I set up a dedicated library for the pose slides, spent all day sorting and rating them into a collection, and now I can't use it.
