title: Facebook Graph API - How do you retrieve the different size photos from an album?
body: <p>Ok, first off let me tell you I have no problems getting a user's photo album(s) and looping through the output to display all of the photos in the size I want. </p>
  
  <p>However, if I want to call a photo like:</p>
  
  <pre><code>&lt;img src="https://graph.facebook.com/&lt;?=$this-&gt;session-&gt;page-&gt;photo_id?&gt;/picture?access_token=&lt;?=$this-&gt;session-&gt;member-&gt;facebook_access_token?&gt;" /&gt;
  </code></pre>
  
  <p>I cannot figure out how to tell it the size I want it to show.</p>
  
  <p>In this sample code from Facebook you will see that whey retrieving the album each photo in the array comes back with the different sizes in this sample array. I could just save the thumbnail url from this, but I don't want to store it, just retrieve when needed.</p>
