title: Post message with picture to facebook page/feed using graph api
body: <p>I'm trying post an a message with one image via facebook graph API, and I can't. In new documentation <a href="https://developers.facebook.com/docs/graph-api/reference/v2.1/user/feed" rel="noreferrer">https://developers.facebook.com/docs/graph-api/reference/v2.1/user/feed</a>
  there is no field for an image. </p>
  
  <p>If I try to use a field "object_attachment", only small thumbnail appears and post is styling like a share link.</p>
  
  <p>If I try to use a field "picture", and use url of photo in the internet there is the same result. I can't post "picture" from local,as here:</p>
  
  <pre><code>$post['picture'] = '@' . realpath($image);
  </code></pre>
  
  <p>error appears: "picture URL is not properly formatted".</p>
  
  <p>I just used a free web app to make a post with a photo, and result is just right(see attached image)</p>
  
  <p>Please tell me, how can I make a post with the exact result?</p>
