create you own captcha

Somedays ago i’ve found a php captcha script from one of my php boss bhaia.But i don’t understand why his script does not work in my local server.But whatever i’ve made one of my own with the help of his script.
You can say it,2nd version of his script for me.

here what i’ve got.

<?php
$im = imagecreate(60, 30);
$RandomStr = md5(microtime());

$ResultStr = substr($RandomStr,0,5);
$bg = imagecolorallocate($im, 200, 255, 255);
$textcolor = imagecolorallocate($im, 200, 0, 255);
imagestring($im, 5, 6, 6, $ResultStr, $textcolor);

header("Content-type: image/jpg");
imagejpeg($im);
?>

now name it captcha.php
now if you want to use it in a form or somwhere else you just write this:

<img src="captcha.php"/>

done
