我已停止使用以下代码生成几种Woocommerce图片大小：
function add_image_insert_override( $sizes ) {
unset($sizes['shop_catalog']);
unset($sizes['shop_thumbnail']);
unset($sizes['woocommerce_thumbnail']);
unset($sizes['woocommerce_gallery_thumbnail']);
return $sizes;
}
add_filter( 'intermediate_image_sizes_advanced', 'add_image_insert_override'
）;
但是问题是，当我访问包含这些图像的产品页面时，Woocommerce会尝试每次都生成它们，从而使页面速度非常慢。如何阻止它这样做？
