<h1>CAPTCHA Help</h1>
<p>Some forms on the PHP Bugs website use
<a href="http://www2.parc.com/istl/projects/captcha/"><acronym
title="Completely Automated Public Turing test to tell Computers and Humans Apart"
>CAPTCHA</acronym></a>s in order to avoid our getting spammed.</p>
<?php
if (isset($_SESSION['captcha'])) {
?>
<p>Your CAPTCHA is <img src="/captcha-image.php" alt="CAPTCHA text" />.
If you are having a hard time reading it, reloading this page
will modify how the image looks.</p>
<p>If you are visually impaired, please send a note to the
<?php echo make_mailto_link('webmaster@php.net', 'php-webmaster') ?>
mailing list. Be sure to explain your situation and include all
of the information from the form you are trying to submit.</p>
<?php
} else {

<p>This page provides further information once you view a
form which requires a CAPTCHA.</p>
