Find drupal logged in users friends on Facebook

I have a Drupal website. When a user开发者_开发百科 logs in to my website with his FB account, I need to show his friends who are already a part of the Drupal website or else bring all his friends from FB to the Drupal website and just show their images in a block. Is there any Drupal module already available or any Facebook API I have to use for it?

Try Drupal For Facebook for this. Or it can be done by javascript sdk also. Call Fb.api('/me/friends', {fields: age, birthday..}, access_token="ACCESS_TOKEN") etc.
