Proof of Concept, Failure in Execution :)

So I have user photos showing up (friend photos), but it's only working
on a small set - when I try to use an account with more friends it
hangs. I have to more deeply understand JavaScript callback functions
and work out how to make the database call fit in with the async nature
of node.js, as at the moment the response is executing before I receive
the data back from mongodb.

More work to be done...
