How do I add a picture only to family?

[Colleen]

I want to add a picture of my Mother, Father, and Brother to family. None of them are on facebook, and one is deceased. They are listed in my family section, now I want to put a picture beside their name. How can I do this?
I have tried to add a picture in "family", but there is no option to do that.
