   sorry i didn't read the rules. The code is
   

   // Get URL of first image in a post
   function catch_that_image() {
   global $post, $posts;
   $first_img = '';
   ob_start();
   ob_end_clean();
   $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
   $first_img = $matches [1] [0];
   
   // no image found display default image instead
   if(empty($first_img)){
   $first_img = "/images/default.jpg";
   }
   return $first_img;
   }

   Also what is the loop?
