Hi,

For example in e-mail registration (such as Yahoo mail) usually we must enter image verification. If we do not enter the correct image text, the registration fails.
You can use this to protect your registration page / login page / comment page.
But you need to modify your old PHP script.
I have put an example in the download link.

For example you want to add captcha to your login page.

This is your old "login.php"

PHP Code:

  <?php

$username = $_POST['username'];

$password = $_POST['password'];

 
if ($username == '' || $password == '') {

   header('Location: login-form.php?error=empty')

   exit();

} else {

   // connect to database, etc

}

 
?>

You can modify it into this

PHP Code:

  <?php

session_start();// required

 
$username = $_POST['username'];

????: NamePros.com http://www.namepros.com/code/434273-php-animated-captcha.html
$password = $_POST['password'];

 
// Read the user's input

$captcha = $_POST['captcha'];

 
// Load the captcha class

require_once(dirname(__FILE__).'/animatedcaptcha.class.php');

 
// Create captcha object

$img = new animated_captcha();

$img->session_name = 'my_turing_test';

$img->magic_words('i am cool');

 
// Regenerate session id on invalid guess

$img->regenerate_session_id(true);

 
$valid = $img->validate($user_guess);// validate user's input

 
if (!$valid) {

????: NamePros.com http://www.namepros.com/showthread.php?t=434273
   header('Location: login-form.php?error=captcha')

   exit();

} else if ($username == '' || $password == '') {

   header('Location: login-form.php?error=empty')

   exit();

} else {

   // connect to database, etc

}

 
?>

Nice, but your images took about a minute to load for me, I am on 3.5 Mb/s connection.
