Captcha

[Dysan]

Hi, I am interested in creating a Captcha script. What do I need to do next?
I have code that generates a single a random 6 character sting, and inserts this into a GD image.

How do I check the image characters with what the user entered in the form?

You can save it in the session and check it when the form is submitted or u can pass the code as hidden variable to send it in the next page. for secure the code you can encrypt the code using md5 when u use a hidden variable.
