Using reCAPTCHA with Google App Engine

java.awt.image.BufferedImage is a restricted class in Google App Engine so there are no support for a Captcha. Try using this external service.

Using reCAPTCHA with Google App Engine


We have no image creation capabilities in Google App Engine (yet). So if you want to display a CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) within a GAE application, you need to do this by using an external service provider.
One of these providers is reCAPTCHA - and the nice thing about reCAPTCHA is, that your visitors are helping to digitize books by solving the CAPTCHA.
