The number of options is extensive, and includes programming a variety of websites from which to get images, re-sizing/filtering images to fit in the display space, choosing local galleries, live webcams, or pre-selected websites (such as National Geographic pic of the day). The downside is the user interface isn't all that clear, and it took me 2 hours just to get a widget with my local slideshow pics in it. Also, there is a bug so that some images are randomly rotated to fit the available space, which isn't very desirable.
