Controller

            //Load Captcha helper
            $this->load->helper('captcha');

                $vals = array(
                    'word'       => 'Security Key words',
                    'img_path'   => './uploads/captcha/',
                    'img_url'    => base_url() . 'captcha/',
                    'img_width'  => 200,
                    'img_height' => 50,
                    'expiration' => 7200,
                );

                /* Generate the captcha */
                $captcha = create_captcha($vals);

                /* Store the captcha value (or 'word') in a session to retrieve later */
                $this->session->set_userdata('captchaWord', $captcha['word']);
                $this->session->set_userdata('captchaImage', $captcha['image']);

                return $captcha['image'];
            }

Here

img_path is the absolute path to your captach folder

img_url is the relative path of the captach image

$vals = array(
    'word'       => 'Security Key words',
    'img_path'   => './uploads/captcha/',
    'img_url'    => base_url() . 'uploads/captcha/',
    'img_width'  => 200,
    'img_height' => 50,
    'expiration' => 7200,
);
