            'img_path'      => './Code__Igniter/application/captcha/',
            'img_url'       => 'http://localhost/Code__Igniter/index.php/captcha/',

        );


        $img = create_captcha($val);

        echo $img['time'];
        echo $img['word'];

        $data['imag'] = $img['image'];  

        $this->load->view('header_view');

        $this->load->view('main_view',$data);

    }
