title: Graph API: Adding Captions To User Generated Photos
body: <p>I'm trying to get my application to post photos to a user's timeline using <a href="https://developers.facebook.com/docs/opengraph/usergeneratedphotos/" rel="nofollow">the user generated picture feature of Open Graph</a>. Unfortunately, while I can easily get the picture to the user's timeline, I haven't found any documented way to pass along a caption.</p>
  
  <p>Instagram seems to have figured it out: <a href="http://i.stack.imgur.com/TYsiX.png" rel="nofollow">http://i.stack.imgur.com/TYsiX.png</a></p>
  
  <p>Yet, if you go to the page of one of their posts, you'll notice that the caption isn't present in any of the Open Graph meta tags, so I'm guessing this is a value passed along with the POST.</p>
  
  <p>Any suggestions? </p>
