Captcha image verification

I have installed the scripts as described and that works great. I need help passing on the form information to my "FormMail.cgi "after verification. What is the proper code to include in the "submit.php" file?
--------------------
Veselin Stoilov: you should either make the submit.php file send the email or make the submit.php post the data to your current FormMail.cgi script.

Hi, i got the script working, but when i change $font_size to 48, the font size remains the same??
I can change it to anything, it wont change!
-----------------------
Veselin Stoilov: I think it is possible that the GD library that you have installed does not support font changes.

Great script. Question though, wouldn't it be a good idea to generate a new CAPTCHA if the validation fails. As you recommend to "rocks" on 2006-09-01 12:48:35, the CAPTCHA would not change when the form is resubmitted. I suppose this is not a big problem, but how would you force the regeneration if the validation failed in this case.

Thanks for informations about image verification. It used in my page.Do you have any ideas to make more secure for mailing system
---------------------------
Veselin Stoilov: the CAPTCHA image verification is one of the best protection methods. Depending on your needs we can also add JavaScript or php validation to your form.

I encountered this error.

PHP Fatal error: Call to undefined function: imagecreatetruecolor() in c:\inetpub\wwwroot\dnet forms\captcha.php on line 9
-------------------------------------
Veselin: this means that your PHP does not have the GD library installed

Hello,

I have the script working but I wanted it to go to my thank you page when successful. The post by Andrew asks the same question. The answer was ("Location: thankyou.html") but where do I put that? Can you please post the submit.php scritp with the Location: thankyou.html in the correct place?

Thanks,
Mike

------------------------------
Veselin: it should look like this
<?
session_start();
if ($_POST["vercode"] != $_SESSION["vercode"] OR $_SESSION["vercode"]=='') {
echo '<strong>Incorrect verification code.</strong><br>';
} else {
header("Location: thankyou.html");
};
?>

------------------------------
Mike: THANK YOU! I am now attempting to combine the captcha scripts with the PHP contact form. I may need some help....let's see what happens.

Nice script! Can you make it display letters as well in the random code?
---------------------------------
PHPJabbers: you can define an array with symbols that you want to use and then select random array elements instead of using rand(10000,99999);
