Problem: I would like to create a Layout for Media attachment pages, but I can't get my image to show up.

Solution: Add the following attachment link shortcode:

add_shortcode('wpv-attachment-link', 'attachment_link_shortcode');
function attachment_link_shortcode ($atts) {
  global $post;
  return wp_get_attachment_image_src($post->ID, $atts['size'])[0];
}

Use the shortcode like so:

[wpv-attachment-image size="large"]

Now each image is displayed as a link to the attachment.
