Product images not displaying correctly after update

Does your child theme declare support for the new single product image gallery that shipped with WC 3.0? More information at https://woocommerce.wordpress.com/2017/02/28/adding-support-for-woocommerce-2-7s-new-gallery-feature-to-your-theme/

Thank you for your reply Riann! I went to the page you suggested and I think I was able to declare the support for the new single product image gallery but I’m not really sure. I pasted my functions.php code below. I already had the remove zoom part in there because I don’t want the zoom function. I’m still having the same problem with my site. I’ve tried using the Site Relic tool to test my site. When I remove this line of code the problem is fixed on Site Relic but I still have the problem when I visit my site from my desktop PC.
remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20 );

Here is my functions.php code. Is there anything I should change in there to try to fix my problem? Thanks again!

<?php

    $parent_style = 'parent-style'; // This is 'twentytwelve-style' for the Twenty Twelve theme.

    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array( $parent_style ),
        wp_get_theme()->get('Version')
