+     *  Adds a CAPTCHA image to the form.
+     *
+     *  <b>Do not instantiate this class directly! Use the {@link Zebra_Form::add() add()} method instead!</b>
+     *
+     *  <b>You must also place a {@link Zebra_Form_Text textbox} control on the form and set the "captcha" rule to it!
+     *  (through {@link set_rule()})</b>
+     *
+     *  Properties of the CAPTCHA image can be altered by editing the file includes/captcha.php.
+     *
+     *  By default, captcha values are triple md5 hashed and stored in cookies, and when the user enters the captcha
+     *  value the value is also triple md5 hashed and the two values are then compared. Sometimes, your users may have
+     *  a very restrictive cookie policy and so cookies will not be set, and therefore they will never be able to get
+     *  past the CAPTCHA control. If it's the case, call the {@link Zebra_Form::captcha_storage() captcha_storage}
+     *  method and set the storage method to "session".
+     *
+     *  <code>
+     *  // create a new form
+     *  $form = new Zebra_Form('my_form');
+     *
+     *  // add a CAPTCHA image
+     *  $form->add('captcha', 'my_captcha', 'my_text');
+     *
+     *  // add a label for the textbox
+     *  $form->add('label', 'label_my_text', 'my_text', 'Are you human?');
+     *
+     *  // add a CAPTCHA to the form
+     *  $obj = $form->add('text', 'my_text');
+     *
+     *  // set the "captcha" rule to the textbox
+     *  $obj->set_rule(array(
+     *      'captcha' => array('error', 'Characters not entered correctly!')
+     *  ));
+     *
+     *  // don't forget to always call this method before rendering the form
+     *  if ($form->validate()) {
+     *      // put code here
+     *  }
+     *
+     *  // output the form using an automatically generated template
+     *  $form->render();
