I am trying to adjust the custom lightbox Wordpress Gallery structure into what I need for my layout. I want to insert a div inside the a-tag, on the same level as the img. By default, Wordpress uses $link to fetch the img, already inside the a-tag, so I would have to be able to fetch these seperately so I can attach my div inside the a-tag.
This is what Wordpress uses to fetch the link:
isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, true, false);
How can I split this up to get the necessary a-tag and img seperately?
