[SOLVED] Using Gd to perform verification.


Recommended Posts



I want to perform a human-verification check on people signing up on my site (you know the things, "type the word" etc). I guess such things are generally Gd but i havent actually got a clue about them.


If anyone could let me in on how to do them, Or if there are any cheap / open versions around, please let me know.


(Advanced PHP user so technical solutions are fine)
