... since, as you point out, we have the instructions

* Usage
*
* For form creation:
* 1 Add [include_once XOOPS_ROOT_PATH."/Frameworks/captcha/formcaptcha.php";] to class/xoopsformloader.php, OR add to the file that uses CAPTCHA before calling XoopsFormCaptcha
* 2 Add form element where proper: $xoopsform->addElement(new XoopsFormCaptcha($caption, $name, $skipmember, ...);
*
* For verification:
* if(@include_once XOOPS_ROOT_PATH."/Frameworks/captcha/captcha.php") {
* $xoopsCaptcha = XoopsCaptcha::instance();
* if(! $xoopsCaptcha->verify() ) {
* echo $xoopsCaptcha->getMessage();
