Well added support for gravatars this morning, man these things are pretty kewl.

If you have are registered on http://site.gravatar.com/ and you use your email address when leaving a comment, then your gravitar is shown next to your name… ;)

This was suprisingly simple to setup… :)

I used MySQL to supply me the MD5 but the solution on there site is:

PHP

Implementing gravatars with PHP is quite simple. PHP provides both md5() and urlencode() functions, allowing us to create the gravatar URL with ease. Assume the following data:

    $email = "someone@somewhere.com";
    $default = "http://www.somewhere.com/homestar.jpg";
    $size = 40;

You can construct your gravatar url with the following php code:

    $grav_url = "http://www.gravatar.com/avatar.php?".
                "gravatar_id=".md5($email).
                "&default=".urlencode($default).
                "&size=".$size;

Once the gravatar URL is created, you can output it whenever you please:

    print("<img src=\"{$grav_url}\" alt=\"\" />");
