title: Retrieving image sent with JSQMessage
body: <p>I am using JSQMessage to create a chat application in Swift, basically my problem is when the user tap the photo I want the photo that is in the chat I want the photo to pop in fullscreen</p>
  
  <p>I will add the steps of what I am trying to do it may be longer but easier to understand. (seems by the sender side, same is valid so the receiver as the image end up in the same array)</p>
  
  <p>Sending the picture:</p>
  
  <pre><code>let sendMessage = JSQMessage(senderId: senderId, displayName: senderDisplayName, media: photoItem) &lt;- Image I am interested is inside here
  self.messages.append(sendMessage)
  self.finishSendingMessage()
  </code></pre>
  
  <p>Great I can see the pic I sent on my screen and now I want to tap on it and I want it to popup full screen (for any of the old photos as well so I am using <code>"didTapMessageBubbleAtIndexPath"</code> here I have <code>println(messages[indexPath.row])</code> here retrieve my JSQMessage object for that message and I can see it has my image on it (as the dump in the end) but I cannot retrieve it.</p>
  
  <p>My question is how can I retrieve this image so I can display it in full screen?</p>
  
  <p>Thanks in advance</p>
