How to add a wrapper element on image for products page

I think I solved, it was simpler than I thought

remove_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_thumbnail', 10);
add_action( 'woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_thumbnail', 10);

/**
* WooCommerce Loop Product Thumbs
**/
if ( ! function_exists( 'woocommerce_template_loop_product_thumbnail' ) ) {
    function woocommerce_template_loop_product_thumbnail() {
        echo "<div class="wc-img-wrapper">";
        echo woocommerce_get_product_thumbnail();
        echo "</div>";
    }
}
