Hi Lucas,

Thanks for your response. Unfortunately, neither 'captcha' => $captchaimage nor 'captcha' => 'My_Captcha_Image' works. You seem to be on the right track, but I get an exception:

Warning: Exception caught by form: Image CAPTCHA requires font Stack Trace: #0 C:\wamp\www\takefoodout\library\TakeFoodOut\Captcha\Image.php(423): TakeFoodOut_Captcha_Image->_generateImage('c60e6c7b5c85f79...', 'r7v5b7wa') #1 C:\wamp\www\takefoodout\library\Zend\Form\Element\Captcha.php(149): TakeFoodOut_Captcha_Image->generate() #2 C:\wamp\www\takefoodout\library\Zend\Form\Decorator\FormElements.php(100): Zend_Form_Element_Captcha->render() #3 C:\wamp\www\takefoodout\library\Zend\Form.php(2595):
...

Here is my code:
<?php
class TakeFoodOut_SignupForm extends Zend_Form
{
public function init()
{
$this->setMethod('post');

// add elements

$this->addElement('captcha', 'captcha', array(
'label' => 'Word Verification',
'description' => 'Please verify that you are human',
'helper' => null,
'order' => 4,
'captcha' => array(
'captcha' => 'Image',
'wordLen' => 6,
'timeout' => 300,
'font' => 'pics/captcha/DeJaVuSansMono.ttf',
'fontSize' => 30,
'imgDir' => 'pics/captcha/img',
'imgUrl' => 'http://takefoodout/pics/captcha/img'
)
));

$this->getElement('captcha')
->addPrefixPath('TakeFoodOut_Captcha', 'TakeFoodOut/Captcha/', 'captcha')
->setCaptcha(new TakeFoodOut_Captcha_Image());

I'm not a Zend form experienced user, and I can't answer you totally...
But after looking Zend_Form_Element_Captcha::setCaptcha() method, I
think something like that :

$captchaimage = new My_Captcha_Image();

$this->addElement('captcha', 'captcha', array(
'label' => 'Word Verification',
'description' => 'Please verify that you are human',
'helper' => null,
'order' => 4,
'captcha' => $captchaimage
));

Would works, because setCaptcha accept both Zend_Captcha_Adapter
instance and options array.
I can also be totally wrong, but maybe try to give to the 'captcha'
index the value 'My_Captcha_Image' instead of 'Image', if you want your
element to instanciate it.

Hope one of this answer will help...
