How to use Captcha image

Hello friends,
Has any one used Captcha image. These images are generally used for authentication.

I am using SimpleCaptcha which by default gives me image containing 5 characters. I have taken one session variable which is used to store these characters. But the session variable contain 6 character.

So while authenticating it always give me invalid match.

If any one has idea about it, please let me know.

I agree. Here's the link:
