A simple example of how to append the raw image URLs to the content of any post or page that has at least one gallery.
/** * Add list of image URLs to the content if displaying a post with one or more image galleries. * * @param string $content Post content. * @return string (Maybe modified) post content. */ function wpdocs_show_gallery_image_urls( $content ) { global $post; // Only do this on singular items. if ( ! is_singular() ) { return $content; } // Make sure the post has a gallery in it. if ( ! has_shortcode( $post->post_content, 'gallery' ) ) { return $content; } // Retrieve all galleries of this post. $galleries = get_post_galleries_images( $post ); if ( ! empty( $galleries ) ) { $image_list = '<ul>'; // Loop through all galleries found foreach( $galleries as $gallery ) { // Loop through each image in each gallery. foreach ( $gallery as $image ) { $image_list .= '<li>' . $image . '</li>'; } } $image_list .= '</ul>'; // Append our image list to the content of our post $content .= $image_list; } return $content; } add_filter( 'the_content', 'wpdocs_show_gallery_image_urls' );Expand full source codeCollapse full source code
