Gravatar is Globally Recognized Avatar, It can be identified by your email address or ID in http://www.gravatar.com/.

The Great WordPress supported gravatar system above version 2.5, we can show the avator icon by the function get_avatar(); I patch my theme (comment.php) this afternoon, and let it supported the gravatar icon. if you wants your WordPress to support the gravatar, please follow the steps:

first, if you don’t have a gravatar, please sign up for one.

second, modify your comment.php in your /wp-content/themes/your_theme/comment.php and insert the function get_avatar(); .

for an example:

    echo get_avatar( $comment, $size = '48', $default = 'url' );

    //   the $comment: just fill the prop. with the variable $comment.
    //   the $size: max is 512
    //   the $default: the default image url, you also can adjust in from your control panel.

WordPress also provided for backwards compatibility(from codex.wordpress.org):

    if (function_exists('get_avatar'))
    {
       echo get_avatar($email);
    }
    else
    {
       //alternate gravatar code for < 2.5
       $grav_url = "http://www.gravatar.com/avatar.php?gravatar_id=" . md5($email) . "&default=" . urlencode($default) . "&size=" . $size;
       echo "<img src='$grav_url'/>";
    }

done! that’s it!
