title: Understanding the realtime api of Instagram - node.js
body: <p>i followed the instructions on <a href="http://instagram.com/developer/realtime/" rel="nofollow">Instagram-Developers-Site</a> step-by-step and managed to subscribe to a hashtag. Now, when my node.js server is up and running i promt <code>req.body</code> to see what i am getting. These are the POST-Requests Instagram is sending me:</p>
  
  <pre><code>[ { changed_aspect: 'media', 
  subscription_id: 2844823, 
  object: 'tag', 
  object_id: 'food', 
  time: 1359561407 } ]
  </code></pre>
  
  <p>This is also as described in the guideline, my question now is:
  What can i do with it?
  I mean i expected a JSON-Object containing all necessary data to display a photo on my page.
  Parameters for example would be: Name, PicURL, Comments, Location, but all i get is this above.
  So can you tell me in which way this information I am receiving is usefull?</p>
  
  <p>So a short summary:
  - I want to display photos of a certain tag on my page
  - using Node and Express
  - PubSub is working
  - I receive that there is a new picture postet but where do i get information about that particular picture?</p>
