Help with php script

[jmaresca]

Hello. I am new to the forum and I am in dire need of some help. I just installed a weight loss tracking script to my site: http://www.lackfat.com/login-register.php

 

if you view the page you will see that the captcha image is no showing up. I have attached the files for the application. hopefully someone can help. Please do reference which files you made changes in so I am able to upload just the files that make the captcha work. Thanks so much!!!
