Picture Window creates slideshows in resizable windows that can be placed in floating windows anywhere on your screen. With this program, your favorite photos are always in view, even when you're using other apps. The app allows you to create slideshows from iPhoto albums and from a folder. Furthermore, the slideshows can be viewed on single, as well as on multiple monitors. What is great about this tool is that it restores slideshows automatically when Picture Window is restarted.
