(About the author)

When you signup on some sites (like paypal.com), they require you to look at a picture and write in a input box what word or characters are in the picture (usualy numbers and letters). They do that so people can't make bots that register multiple accounts in a short period of time. My code will teach you how to add a verification like that to your signup script.

5* from Me

I made a little bug in example script 
(test.php), I hard coded the picture 
URL by mistake. Simply replace 
http://wc3.skreel.org/test.php to 
test.php.
Also, here is what the zip 
contains:
  - ConfirmPNG.php: class 
that generates the picture and stores 
the codes into MySQL.
  - Config.php: 
this contains your MySQL information, 
which you must edit.
  - Test.php: is 
somewhat a SDK on how to use the 
class.
If you have any suggestions, 
let me know.
Thanks.

# Table structure for table

CREATE TABLE 
ezcounter_hashes ( autoid int(11) NOT 
NULL auto_increment, hashid text NOT 
NULL, confnum int(11) NOT NULL default 
'0', KEY autoid (autoid) );

me if I am wrong.
