Tank Auth v1.0 (CI authentication library)

[eluser]pdriggett[/eluser]
Ok, I have just uploaded Tank Auth into what I think are the correct locations and made sure to set up my configs correctly. I see the login page and go to the register page, but no CAPTCHA is showing up at all.

You can see this at www.versustd.com

I have the captcha folder that came with the tank auth .zip and I put it in the root directory at the same level as application. I also tried placing it in the codeigniter folder since his instructions say: "Copy the captcha folder to your CI folder. Make sure this folder is writable by web server."

I have also made sure to make it writable.

Any suggestions?
