I would like to display a random Image in the Hero Background.  I have replaced the code on Line #3 in the  ./views/home.inc

<?php echo $page->hero_unit->image->url?>

with

<?php			if(count($page->hero_unit->images)) {
				$image = $page->hero_unit->images->getRandom();
 	     		echo $image->url;	
}
?>

and it returns a blank hero bg.
