title: cache http://graph.facebook.com/[UID]/picture call?
body: <p>Thanks to <a href="https://stackoverflow.com/questions/3012905/how-can-i-display-the-users-profile-pic-using-the-facebook-graph-api/3012980#3012980">How can I display the users profile pic using the facebook graph api?</a> I found out I can retrieve profile picture via</p>
  
  <pre><code>http://graph.facebook.com/[UID]/picture
  </code></pre>
  
  <p>but this redirects to an image like for example:</p>
  
  <p><a href="http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs1346.snc4/161671_1096373372_1486835_q.jpg" rel="nofollow noreferrer">http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs1346.snc4/161671_1096373372_1486835_q.jpg</a></p>
  
  <p>My first question is when I want to display this image should I do(returned from API)</p>
  
  <pre><code>&lt;img src="http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs1346.snc4/161671_1096373372_1486835_q.jpg" /&gt;
  </code></pre>
  
  <p>or should I call the api:</p>
  
  <pre><code>&lt;img src="http://graph.facebook.com/alfredwesterveld/picture" /&gt;
  </code></pre>
  
  <p>Does <a href="http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs1346.snc4/161671_1096373372_1486835_q.jpg" rel="nofollow noreferrer">http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs1346.snc4/161671_1096373372_1486835_q.jpg</a> show my updated profile picture, if update my profile picture on Facebook or does show my old profile picture. I ask these question because when I could call an absolute URL(which resolves to an image immediately) I could safe myself a redirect(round-trip). I believe this could add up especially when I want to get all profile pictures from the visitors of my website.</p>
