Unfortunately, I was in a rush to get it done and didn't take notes. I 
do remember now that the true type fonts were not installed on the 
machine either so I copied one over from a windows machine. Here's a 
list of pear stuff installed:?
?

Installed packages, channel pear.php.net:?

=========================================?

Package        Version   State?

Archive_Tar    1.3.1     stable?

Console_Getopt 1.2       stable?

Image_Text     0.6.0beta beta?

PEAR           1.4.9     stable?

Text_CAPTCHA   0.3.1     alpha?

Text_Figlet    1.0.0     stable?

Text_Password  1.1.0     stable?

XML_RPC        1.4.8     stable?
?

Here's  a snippet of code that works (for me):?
?

<?php?
?

require_once 'Text/CAPTCHA.php';?

session_start();?
?

$captcha = Text_CAPTCHA::factory('Image');?

$options = array('font_size'=>'20',?

?      'font_path'=>'/home/webdir/',?

?      'font_file'=>'VERDANA.TTF');?

$captcha->init(150, 60,NULL,$options);?

$image = $captcha->getCAPTCHAAsJPEG();?

file_put_contents('captcha.jpg', $image);?

$_SESSION['captcha_phrase'] = $captcha->getPhrase();?
?

?>?
?

The captcha has succeeded in stopping any futher spam from hitting my 
clients comment board. I've read, however, that something as simple as a 
fixed image and a request to retype the displayed word is sufficient 
(http://www.codinghorror.com/blog/archives/000712.html)?
