Any way at all of making the featured image a link to its media file in posts?

[Michael]

So I’d like to show the featured image in a certain category of posts (elsewhere it is in the header). But ideally, due to the nature of the posts, I’d like users to be able to click the featured image so my lightbox will show it larger.

Possible at all?

Hi there,

try this PHP snippet:

add_filter( 'post_thumbnail_html', 'db_post_thumb_media_link', 10, 3 );
 
function db_post_thumb_media_link( $html, $post_id, $post_image_id ) {

    if ( !is_single() ) {
        // Return default if NOT single
        return $html;      
    } else {
        // Get URL of large image attachment
        $large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'large');
        // Wrap HTML in link
        $html = '<a href="' . $large_image_url[0] . '">' . $html . '</a>';
        return $html;
    }
}
