Hi,
I am trying to set up an image verification system for a registration page, however I keep getting the following parse error:
Parse error: parse error, unexpected T_STRING in /homepages/41/d171489552/htdocs/image_verification/form1.php on line 3
Even when I remove the header I get an error...
I'm relatively new to PHP, so it might be something silly, but any help would be greatly appreciated.
Thanks!

Here is the code:
<?php
/header*/
Header("Content-Type: image/png");
/ initialize a session. /
session_start();
/We'll set this variable later./
$new_string;
/register the session variable. /
session_register('new_string');
/You will need these two lines below./
echo "<html><head><title>Verification</title></head>";
echo "<body>";
/ set up image, the first number is the width and the second is the height/
$im = ImageCreate(200, 40);
/creates two variables to store color/
$white = ImageColorAllocate($im, 255, 255, 255);
$black = ImageColorAllocate($im, 0, 0, 0);
/random string generator./
/The seed for the random number/
srand((double)microtime()*1000000);
/Runs the string through the md5 function/
$string = md5(rand(0,9999));
/creates the new string. /
$new_string = substr($string, 17, 5);
/fill image with black*/
ImageFill($im, 0, 0, $black);
/writes string */
ImageString($im, 4, 96, 19, $new_string, $white);
/ output to browser/
ImagePNG($im, "verify.png");
ImageDestroy($im);
echo "<img src=\"verify.png\">";
echo "<br><br>";
echo "Type the code you see in the image in the box below. (case sensitive)";
echo " <form action=\"formhandler.php\" method=post>";
echo "<input name=\"random\" type=\"text\" value=\"\">";
echo "<input type=\"submit\">";
echo "</form>";
echo "</body>";
echo "</html>";
?>
