At home I have a picture of the kids that I took for the Christmas cards (that needs to be updated.
) I generally have some recent photo of them but it's hard to get a good group one now that I am up to three little ones!
My work computer has a photo of a lake that I took last fall. I wanted to see what kind of resolution my phone's camera had and apparently it is good enough to be wallpaper on a 1600x1200 pixel display!
My netbook has the default wallpaper. I don't really have any plans to change it.
