title: GraphAPIError: (#324) Requires upload file
body: <p>I'm trying to upload a picture with the python sdk:</p>
  
  <p>Code:</p>
  
  <pre><code>graph = facebook.GraphAPI(self.current_user.access_token)
  graph.put_object("me", "photos", name = "test", message = raw_picture_data)
  </code></pre>
  
  <p>But I get the error <code>"GraphAPIError: (#324) Requires upload file"</code>. I don't think its a permissions issue as I've requested perms="user_photos,friends_photos,publish_stream". Does anyone know what this error means and how to resolve it?</p>
