title: Not getting all the photos user is tagged in facebook
body: <p>I am comparing my results with the graph api explorer. I have a dummy account with 6 tagged pictures of mine. 
  From iOs using FBGraph i get access token with permission "user_photos"</p>
  
  <p>On calling me/photos I get back only one photo. </p>
  
  <p>If i generate access token from graph api explorer with same "user_photos" permission, i get back all 6 photos. </p>
  
  <p>Can anyone enlighten me why do I not get all the photos I am tagged in.</p>
  
  <p>Regards</p>
