Your Captcha is almost done! This Fake Captcha won't be able to tell computers and humans apart like a real Captcha. (Did you know that Captcha stands for "Completely Automated Public Turing Test to Tell Computers and Humans Apart"?) It will look just like a captcha image and allow to do all sorts of interesting things with the fake captcha image generator!
Maybe you need a fake captcha as a design placeholder instead of the stock image captcha? A fake captcha image will give your design mockup a more custom look.
