如何从删除按钮中的codeigniter中删除上传文件夹中的图像文件？任何人都可以指导我吗??? 这是我的上传图像文件的控制器

private function upload() {
    $config['upload_path'] = 'assets/uploads/orginal/';
    $config['allowed_types'] = 'gif|jpg|png|jpeg|x-png';
    $config['max_size'] = '500';
    $config['max_width'] = '1600';
    $config['max_height'] = '1200';
    $config['remove_spaces'] = TRUE;
    $this->load->library('upload', $config);
    if ($this->upload->do_upload()) {
        $img = $this->upload->data();
        // create thumbnail
        $new_image = 'assets/uploads/thumbs/' . $img['file_name'];

        $c_img_lib = array(
