Can I use the Facebook graph api to get user's friends profiles pictures?

Easiest way yet was not posted here:

https://graph.facebook.com/me/friends?access_token=[oauth_token]&fields=name,id,picture

You first have to get the list of friends https://graph.facebook.com/me/friends?access_token=... then for each of the friends you can request http://graph.facebook.com/user_id/picture That will give you the url of their current profile photo.
