Very simple and basic

This pure-ASP freeware random number distorted image generation script (generically know as CAPTCHA) is very easy to implement (5/5) and the image is of average quality (3/5). Upon calling the aspcaptcha.asp into an image tag, a session variable is generated.
The script generates numeric characters only, is monotone red, and distorion (which is customizable) is limited to horiz and vert shift, with backgrd noise (pixels).
