<h2>Secureimage PHP Requirements Test</h2>
<p>
  This script will test your PHP installation to see if (Secureimage) CAPTCHA will run on your server.
  <br /><br />
Note: If you see any errors or warnings at the top of the page,
especially "Warning: session_start...", they could be indicating a problem with your PHP server that will prevent the CAPTCHA from working.
