Captcha doesn't work correctly in Railo using CFIMAGE

Question

Hello,

I was playing around with CAPTCHA in Railo using CFIMAGE recently and for some reason I couldn't make it work correctly. It generates the image and it shows up in the browser, but the font looks strange and the letters are placed all over, usually one half on top and the other on the bottom of the image.

Here's my code:

And this is what it generates: http://lecws.com/captcha.cfm

Is there anything I'm missing? Do I have to install fonts on the server? I'm running Railo 3.1.2.001 final on CentOS 5.3 64bit. Any help is appreciated.
