I think a person's choice in picture can say a lot about them. I know that the pictures are mainly how I think about a person. I am a visual person and tend to see their avatar in my head. They can also tell about a person's personality and what interests them. I have a Klimt painting which says a lot about my aesthetic taste. Other people have pictures from movies they are fond of or funny things they have found.

Basically I think that since an avatar is a conscious choice that appeals to someone enough to make it a part of their online persona then it must say something about someone... even if it is only that they like cats.
