I’m writing a review of Posterino for MacUser. It’s fun to play with. This is the very first image it made for me, which I exported without edits. Posterino picked all these images randomly from my iPhoto archive, and did a pretty good job. There are only a few rogue images - two portrait-style shots, and one family snapshot that appears to have been used twice. Other than that, a delightful and almost instantaneous round-up of photos.
