use any url in gallery shortcode

This is how $result output:
source=”media:http://page.no/wp-content/uploads/2016/01/ringve-museumfpprojslideimg2-1.jpg,http://page.no/wp-content/uploads/2016/01/ringve-museumfpprojslideimg.jpg”

This is my code

<?php
						$result = types_render_field("prosjektbilder", array("raw"=>"true","separator"=>",", "get_id"=>"true"));

						$result_shortcode = '[su_custom_gallery source="media:'.$result.'" link="lightbox" width="150" height="150" title="never"][su_custom_gallery link="lightbox" width="80" height="80" title="never"][/su_custom_gallery]';

						/* echo do_shortcode( .'$result_shortcode'.  );  */
						echo $result_shortcode;
							   ?>

Anyone know how I can use this shortcode with image urls?
