I use the Astronomy Picture of the Day as the home page for my browser. Whenever there's a picture I particularly like, I copy it into a special folder. I use the desktop background slide show feature to pull pictures from this folder, changing them every six hours. I currently have about 250 pictures in there. Here is the main page and a few examples:

http://apod.nasa.gov/apod/ap110511.html
http://apod.nasa.gov/apod/ap120402.html
http://apod.nasa.gov/apod/ap111225.html
http://apod.nasa.gov/apod/ap000420.html
http://apod.nasa.gov/apod/ap120625.html
http://apod.nasa.gov/apod/ap001118.html
Clicking on the picture itself will usually give you a larger version.
