A question about images

Just something I've been musing on recently. When you personalise your desktop, what kind of images do you use?

I ask mostly because both my sisters seem to mostly use fannish images, and I ... sort of don't. Neither do my parents, but they seem to use personal photographs (or the free images that come with the laptop, but in her defence, some of those are genuinely nice), rather than other images. I don't really do either.
