Function wpgs_product_image()

Hi.

You had function wpgs_product_image() but now it not exists in plugin, so I cannot use it like this in our theme

remove_action( 'woocommerce_before_single_product_summary', 'wpgs_product_image', 20 );
add_action( 'my_another_hook', 'wpgs_product_image', 20 );

The plugin now has initialization like this

    public function hooks()
    {
        remove_action('woocommerce_before_single_product_summary', 'woocommerce_show_product_images', 20);
        remove_action('woocommerce_product_thumbnails', 'woocommerce_show_product_thumbnails', 20);
        add_action('woocommerce_before_single_product_summary', [$this,'wpgs_product_image'], 20);
        add_action('woocommerce_product_thumbnails', [$this,'wpgs_product_thumbnails'], 20);
    }

but I unable to get object reference, created in a way
new Product(); and use callback [$this,'wpgs_product_thumbnails']

Could you please put the references in a constant or any global variable, so I’m be able to use it like this

add_action( 'my_another_hook', [ $instance, 'wpgs_product_image' ], 20 );

Thank you
