Image authentication (like in yahoo)
Posted: Sat Aug 19, 2006 9:43 am
I was curious on how to make 'image authentication' (like one you see when you sign in a yahoo mail).
I was wondering how could the server (or maybe the code) generates an image of distorted random string like that.
Is there anyone who knows how to build this? Or at least a link I can donwload from?
Thx b4.
