    Hello,

    In WordPress 3, is there a way to link a post thumbnail directly to the location of a full size image inside the same post?

    I’m looking at making a dynamic lightbox-enabled thumbnail gallery page from posts of different categories, but am confused on how to make them open to a full sized image view.

    Thank you,

    Nevermind, I found the function needed to achieve this from https://webdeveloperplus.com/

    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];

  if(empty($first_img)){ //Defines a default image
    $first_img = "/images/default.jpg";
  }
  return $first_img;
}
