image\\u make\\u intermediate\\u size不是我要找的挂钩，而是intermediate\\u image\\u size\\u advanced。

以下是工作代码：

function disable_upload_sizes( $sizes, $metadata ) {

    // Get filetype data.
    $filetype = wp_check_filetype($metadata[\'file\']);

    // Check if is gif. 
    if($filetype[\'type\'] == \'image/gif\') {
        // Unset sizes if file is gif.
        $sizes = array();
    }

    // Return sizes you want to create from image (None if image is gif.)
    return $sizes;
}   
add_filter(\'intermediate_image_sizes_advanced\', \'disable_upload_sizes\', 10, 2);
