Live Demo
There are a few links below to help you try different captchas. On the top of each demo page there is a one-line form with a text box. That is NOT part of the captcha, it simply represents your web form. The green "submit" button does NOT belong to the captcha either. That one symbolizes the submit button of your website's form. Once the captcha is solved, click the red button to verify your answer. After verification, you can submit the form by clicking the green "submit" button. The Bent arrow button gives you a new captcha challenge.
