Okay... but is datatree_order actually being used for anything at the 
moment?  Should the following code work to set the order, then?


$neworder = Util::getFormData($id . '_order');
$image->data['order'] = $neworder;
$image->update();

Will this be automatically reflected in the gallery display, or do I 
have to make modifications to the gallery display code to be "order" aware?

Thanks,
