Modify the Pinterest loop for posts/pages without thumbnail images

The following is sample code that you could use. The problem: a post/page without a thumbnail image will send a null image to Pinterest. The solution: if the post/page has no featured image, find the first image on the post/page content and use that for Pinterest submission.

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;
}
