I use John’s Background Switcher (www.backgroundswitcher.com) which means I can have Flickr photos as my background and they automatically change. I use all the Flickr photos I have as “Favourites” which makes for wonderful eye candy.
I also use Slickr (http://cellardoorsw.com/?page_id=4) for my screensaver which also uses Flickr photos, but for this one I use my own photos uploaded to Flickr. The benefit of this is that it is like a slideshow the kids can watch with photos of themselves and the family.
Both of these can also use photos from your own computer.
