Displaying Icons in Component Boxes

This isn't really a question about making icons (but it does have to do with icons). I've noticed a lot of people displaying their favorite user pics in a component box on their journal (those using the component layout that is) like saava does. I was wondering how one goes about doing this. I've looked in the edit customizations area and can't find it as an option. Anyone have any clues?

Thanks! :)
