Simple, easy powerful
Just bought this app and made a dozen collages in a row. Very intuitive: I just dragged-and-dropped from iPhoto, then after saving I dragged new photos on top of the old ones and the new photos replaced the old. Easy!
Near the very end of my dozen montages the app crashed once, but on relaunch it brought me right back to where I was with the photos still there, so no biggie. Easily worth the 99¢ price!
