Setting a Desktop Picture
I am attempting to set a desktop picture. I want to use a picture that is in my iPhoto library. I thought that the area I have delineated with the red rectangular border would give me access to all the photos that are in iPhoto but no - it is just a subset. I would say that about 30% of the photos are available in this window. What gives? How is it that I don't have access to all the photos in iPhoto in this window?
