   Hey

   When you upload a picture to the media library, WP generates a thumbnail (size set by you) that itself uses when you look inside your media library.

   Is there a way to extract that? I am using a catch-that-first-image-in-the-post function but I dont know PHP that well and I wanted to know if there is a better way to do it.

   The function I use is:

   function catch_that_image() {
     global $post, $posts;
     $first_img = '';
     $nothumb = get_bloginfo('template_directory');
     ob_start();
     ob_end_clean();
     $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
     $first_img = $matches [1] [0];
   
     if(empty($first_img)){ //Defines a default image
       $first_img = "$nothumb/images/default.jpg";
     }
     return $first_img;
   }

   Can it be changed to load the thumbnail of the first image instead?
   Thanks in advance.
