Fixes the add_to_image_queue bug that halts this addon from working

So if a post has a noninlined photo or a photoset, any subsequent posts that are loaded will throw an exception being unable to call add_to_image_queue (as it is an embedded document command [to call it we would have to use eval, which is bad for what we are trying to accomplish]).

The call isn't important and can be safely stripped out of the response.
