你想要的可能是这样的。

您需要手动取消链接原始图像，包括添加的大小。

WP图像编辑器会自动使用您提到的新名称创建一个新图像，但不会使用其他通过add_image_size() 作用

regenerate_added_sizes() 在下面的代码中，它正是这样做的：

function replace_original_images( $override, $filename, $image, $mime_type, $post_id ) {
    if ( \'image/jpeg\' !== $mime_type && \'image/png\' !== $mime_type ) {
        return $override;
    }
    $image_meta = wp_get_attachment_metadata( $post_id );
    $upload_dir = wp_upload_dir();

    $original_file_path = path_join( $upload_dir[\'basedir\'], $image_meta[\'file\'] );

    // \'full dir\' includes year and mouth location
    $upload_full_dir = str_replace( basename( $original_file_path ), \'\', $original_file_path );

    // delete original image
    unlink( $original_file_path );

    // delete other sizes
    foreach ( $image_meta[\'sizes\'] as $size ) {
        unlink( $upload_full_dir . $size[\'file\'] );
    }
    // regenerate added sizes
    function regenerate_added_sizes( $meta_id, $object_id, $meta_key ) {
        if ( \'_wp_attachment_metadata\' !== $meta_key ) {
            return;
        }
        $image_meta = wp_get_attachment_metadata( $object_id );
        $upload_dir = wp_upload_dir();

        $new_file_path = path_join( $upload_dir[\'basedir\'], $image_meta[\'file\'] );

        // prevent infinite loops
        remove_action( \'updated_post_meta\', \'regenerate_added_sizes\' );

        update_post_meta( $object_id, $meta_key, wp_generate_attachment_metadata( $object_id, $new_file_path ) );
    }
    add_action( \'updated_post_meta\', \'regenerate_added_sizes\', 10, 3 );

    return $override;
}
add_filter( \'wp_save_image_editor_file\', \'replace_original_images\', 10, 5 );
