Adding captcha to Perl - cgi email form...

I would like to add the captcha that can be found here: [login to view URL] Feel free to modify their captcha solution but I want to make certain the captcha images have a white background with dark lettering. Acceptable: [login to view URL] [login to view URL] Not Acceptable: [login to view URL] [login to view URL] To make this project clear, I posted the code in the following thread: [login to view URL] Unfortunately, I doubt I'm going to get the help needed there so that's why I'm posting here. Also, VERY IMPORTANT. Please bid in complete confidence. I just got burned on my last project here. Sincerely, Errica
