title: Get instagram picture
body: <p>Does anybody know how to retrieve and Instagram picture?
  I mean like users fill in the link on my site of the picture e.g.http://instagram.com/p/RTqrWXkEme/ (does not exist just example) and then I show them the picture only</p>
  
  <p>I'm sure this works via Instagram's API but I have no idea how..</p>
  
  <p>Kind regards</p>
