hi i am trying to upload images from my wp8.1 app to facebook but one of the issues is that pictures posted are visible to only me unless i amnually change it from facebook . i want to post them automatically for public to view . here is my code :
 var postParams = new
        {
            access_token = ObjFBHelper.AccessToken,
            message = "My message",
            source = pic,
        };
  try
     {
       dynamic fbPostTaskResult = await    fbclient.PostTaskAsync("me/photos",postParams);
     var responseresult = (IDictionary<string, object>)fbPostTaskResult;
        }
        catch (Exception ex)
        {
            //MessageDialog ErrMsg = new MessageDialog("Error Ocuured!");
        }
