Hello @paul614724,

As currently there is no light box feature included in the theme you have to add below given code in your child theme functions.php file .

You can even activate the child theme using the plugin given below :

https://wordpress.org/plugins/wp-child-theme-generator/

After activating the child theme in your child themes functions.php file please add below given code.

add_action( 'after_setup_theme', 'travel_eye_pro_setup' );
 
function travel_eye_pro_setup() {
    add_theme_support( 'wc-product-gallery-zoom' );
    add_theme_support( 'wc-product-gallery-lightbox' );
    add_theme_support( 'wc-product-gallery-slider' );
}

Hope this helps .

Best Regards!!
