Have you noticed the little "People" at the bottom right of the Reading Pane when you are viewing a message? These are the recipients - click the arrow next to them to expand the People Pane and see recent activity (emails, meetings,...) relating to those people. if you add someone to your Contacts folder and include a photo, their photo will appear in the People Pane when you receive a message from them.
