Reply To: Product image Gallery Thumbnail Size and Number.

Hello,

Please try to add this code to the functions.php of the 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'          => 6,
					'tablet_landscape' => 3,
					'tablet'           => 4,
					'mobile'           => 3,
					'vertical_items'   => 3,
				),
			),
		);
	}
);

Best Regards
