add_filter( 'the_content', 'wpdocs_show_gallery_image_urls' );

function wpdocs_show_gallery_image_urls( $content ) {
    global $post;

    if( ! is_singular() ) return $content;

    if( ! has_shortcode( $post->post_content, 'gallery' ) ) return $content;

    $gallery = get_post_gallery_images( $post );

    $image_list = '<ul>';

    foreach( $gallery as $image_url ) {
        $image_list .= '<li>' . '<img src="' . $image_url . '">' . '</li>';
    }

    $image_list .= '</ul>';

    $content .= $image_list;

    return $content;
}
