Hello,

In order to display 10 thumbnail images, try adding the below code to the functions.php file in your child theme.

add_filter(
    'woodmart_product_gallery_settings',
    function() {
        return array(
            'images_slider' => woodmart_is_main_product_images_carousel(),
            'thumbs_slider' => array(
                'enabled'  => woodmart_is_product_thumb_enabled(),
                'position' => woodmart_get_opt( 'thums_position' ),
                'items'    => array(
                    'desktop'          => 10,
                    'tablet_landscape' => 3,
                    'tablet'           => 4,
                    'mobile'           => 3,
                    'vertical_items'   => 3,
                ),
            ),
        );
    }
);

Later you can change the number of pictures by setting another value for the “desktop” field (https://prnt.sc/2651z4q).
