Captcha Plugin -> Borked?

[eluser]llbbl[/eluser]
Hey everyone. I was just wondering if anyone got the captcha plugin that comes with codeigniter to work? I been messing around with it today and can't get the function create_captcha() to return any values.


I noticed that freakauth uses the Image_lib library to generate their captchas...

Code:

INSERT INTO captcha (captcha_id, captcha_time, ip_address, word) VALUES ('', NULL, 'XXX.XXX.XXX.XXX', NULL)

IP address works but its not returned by the function. I XXXed out what my IP is
