I suggest you try the php gravatar class by Lucas Araújo.
/**
* Class Gravatar
*
* From Gravatar Help:
* "A gravatar is a dynamic image resource that is requested from our server. The request
* URL is presented here, broken into its segments."
* Source:
* http://site.gravatar.com/site/implement
*
* Usage:
* <code>
* $email = "youremail@yourhost.com";
* $default = "http://www.yourhost.com/default_image.jpg"; // Optional
* $gravatar = new Gravatar($email, $default);
* $gravatar->size = 80;
* $gravatar->rating = "G";
* $gravatar->border = "FF0000";
*
* echo $gravatar; // Or echo $gravatar->toHTML();
* </code>
*
* Class Page: http://www.phpclasses.org/browse/package/4227.html

}
and this is how you'd use it:
include 'gravatar.php';
$eMail = 'name@email.net';
$defImg = 'http://www.example.com/images/myphoto.jpg';
$avatar = new Gravatar($eMail, $defImg);
$avatar->setSize(90);
$avatar->setRating('G');
$avatar->setExtra('alt="my gravatar"');
<p>
<?php echo $avatar->toHTML(); ?>
</p>
