Use last gallery image as product thumbnail in a specific products carrousel

Hello,

Unfortunately, this will not work using a custom class. All we can provide you with is the following custom code, which will change the main product image on all carousels to the last one from the gallery.

add_action('woodmart_get_product_thumbnail', function ($img, $product, $size, $attach_id) {
	if ( woodmart_loop_prop( 'is_slider' ) && doing_action('woocommerce_before_shop_loop_item_title') ) {
		$images = $product->get_gallery_image_ids();

		$image_id = end( $images );

		$custom_size = $size;
		if ( woodmart_loop_prop( 'img_size' ) ) {
			$custom_size = woodmart_loop_prop( 'img_size' );
		}

		$custom_size = apply_filters( 'woodmart_custom_img_size', $custom_size );

		$img = woodmart_otf_get_image_html( $image_id, $custom_size, woodmart_loop_prop( 'img_size_custom' ) );
	}

	return $img;
}, 10, 4);

Kind Regards
