I tried the free version of this Mac App to see pictures and I think it's fantastic! https://itunes.apple.com/us/app/movingphotos3d-free/id463203523?ls=1&mt=12 Now I have the full version (and the screensaver) all run perfectly in my OS MountainLion on iMac 27". IMO this is a new multimedia way to see the pictures. I think this can be perfect also for theprofessional use to show pictures to the client. And this is a way to pass time with friends at home like viewing slides with the projector so much time ago... 5 euros well spent !!! (but it worth much much much more - this is an extension of my chain: camera - monitor - viewing method). Cheers, Peter.
