Displaying profile pictures in all connected devices

Basically I am working on multiplayer Tic Tac Toe game. I have added face book connectivity to play with friends. Now I want to display profile picture on screen to each connected player.

Now I am stuck at how to display two connected players picture on each device? Means I can able to see my friends picture on my device screen to whom I am playing. So how to manage this condition? Whether I have to use any web service for this or not?

Please give some suggestions in this?
