您可以使用“intermediate\\u image\\u sizes”过滤器禁用中图像和大图像大小：

function remove_image_sizes($image_sizes){
    foreach($image_sizes as $key => $size){
        if($size == \'large\' || $size == \'medium\')
            unset($image_sizes[$key]);
    }
    return $image_sizes;
}
add_filter(\'intermediate_image_sizes\', \'remove_image_sizes\', 12, 1);
