few
great articles on

Jeff talks about using HttpHandlers and HttpModules to do the image creation. He also gives a .Net 1.1 and 2.0 framework version. It includes a time out and even hides the actual text of the Captcha outside of the viewstate, since we all are aware the viewstate can easily be decoded.
