How can I post an uploaded photo to a user’s wall/feed?

My application generates an image with the name of the user and some information. It looks like a certificate. I upload this image to the user’s profile, but it doesn’t appears on the feed. So the friends don’t see that. I tried to post it with – 

$post = $facebook->api('/me/feed', 'POST', array(...));

But I realized, that I can’t post Facebook hosted photos. But there are many applications on Facebook that generate images, uploads them and posts them to a wall. But how?

    You can post facebook-hosted pictures onto the user’s wall. You need to do a simple wall post, and include the object_attachment parameter, which contains the picture’s id. It is documented here, near the bottom of the table.

    You can find more details in this blogpost. It also contains the following example:

    <?php
  $app_id = "APP_ID";
  $app_secret = "APP_SECRET";
  $post_login_url = "POST_AUTH_REDIRECT_URL";
  $photo_id = "PHOTO_ID";
  $wall_message = "MESSAGE_FOR_POST";
  $wall_link = "LINK_TO_POST";
  $user_id = "USER_ID";

  $code = $_REQUEST["code"];

  // Obtain the access_token with publish_stream permission 
  if (!$code) {
    $dialog_url= "http://www.facebook.com/dialog/oauth?"
      . "client_id=" .  $app_id
      . "&redirect_uri=" . urlencode( $post_login_url)
      .  "&scope=publish_stream";
    echo("<script>top.location.href='" . $dialog_url
      . "'</script>");
  } else {
    $token_url="https://graph.facebook.com/oauth/access_token?"
      . "client_id=" . $app_id
      . "&redirect_uri=" . urlencode( $post_login_url)
      . "&client_secret=" . $app_secret
      . "&code=" . $code;
    $response = file_get_contents($token_url);
    $params = null;
    parse_str($response, $params);
    $access_token = $params['access_token'];

    // POST to Graph API feed endpoint, which is the user's Wall
    $graph_url= "https://graph.facebook.com/" . $user_id . "/feed?"
      . "message=" . urlencode($wall_message)
      . "&link=" . urlencode($wall_link)
      . "&object_attachment=" . $photo_id
      . "&method=POST"
      . "&access_token=" .$access_token;

    echo '<html><body>';
    echo file_get_contents($graph_url);
    echo '</body></html>';
  }
?>
