如何将照片上传到群组？

Question

Here's how I'm attempting to upload a photo (and please tell me if I can improve this):

var feedPath = String.Format( "/{0}/photos/", feedId );
dynamic parameters = new ExpandoObject();

try {
  var fbUpl = new Facebook.FacebookMediaObject {
    FileName = photoUrl,
    ContentType = "image/jpg"
  };

  var bytes = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath(photoUrl));
  fbUpl.SetValue(bytes);
  parameters.message = msg;
  parameters.source = fbUpl;

  dynamic fbResult = fbApp.Post(feedPath, parameters);
}
catch (Exception exc) {...}

This will upload to the user's wall. However, if I substitute the feedId with the group's id, it does not post to the group. How do we post photos to groups (on behalf of the currently authenticated user)?

First you need to get a manage_group permission...

But there is a bug what I submitted last year : http://bugs.developers.facebook.net/show_bug.cgi?id=19157

After Facebook fix that, you get a manage_group permission. Then only need to use the group_id as normal user_id to take actions.
