DRBImageVerification
- DRBImageVerification is a simple anti-spam image verification, or &"CAPTCHA&", script. It allows you to add a challenge-response test to your existing PHP powered forms to prevent automated spam postings. The verification string length and character list are configurable. The script requires a session cookie for additional obscurity. It includes an example PHP page demonstrating how to add a verification image to an existing form.
