You need an image to generate the Captcha random letters, store that
generated string in the $_SESSION super globals ($_SESSION['Captcha']
or something like this) and then, check the input from the form
against the $_SESSION.

The image with the random captcha text can be created with php built-
in function to manip images. Then on your form, you just need to add
the captcha image something like: <img src="captcha.php" /> and that
captcha.php file should generate the image and set the text in the
session.

At least, thats my way...
