I found a pretty small and useful open source application that pulls images from Google images in a given interval and displays them as the wallpaper on the pc the application is running. Once unrared you can run the application right from that location without installation; you will see a small icon in your system tray if the application is running. Right-click the icon and select options.
Add some keywords that should be used to search for new images, select if you want surfer friendly images only and define the change rate in minutes. You can try it out immediately by right-clicking the icon again and selecting Update Now. This takes a few seconds but the wallpaper should change into a random image that was pulled from Google. The software will only search for high quality images that fit nicely on most screens.
I suggest you add at least 5-10 keywords to receive enough images to avoid repetition. The application pulls the images only from the first page of results and picks a random image from that page which means you have a chance of 1 in 18 that the same picture will be picked again as the wallpaper.
