Image Verification
I'm sure all of you have gone to an email and when your logging in you get a message saying to verify the words in the box.
This is for security so people can not make "bots" automatily sign-up for a service or send massive amounts of emails.
You need PHP and the GD Library. (X10 has this installed)
Create a php file and name it verification.php inside post this code.
<FONT style="BACKGROUND-COLOR: #ffffff">
Then create another file this time named form.php inside post this code.
<FONT style="BACKGROUND-COLOR: #ffffff">
