-for gravatar support edit comments.php inside theme folder and replace this:

comment_type) {

echo 'comment_author_email);

echo '" alt="'.$comment->comment_author.'" width="40" height="40" />';

} elseif ( ('trackback' == $comment->comment_type) || ('pingback' == $comment->comment_type) ) {

echo 'comment_author_url);

echo '" alt="'.$comment->comment_author.'" width="40" height="40" />';

}

} else {

//echo 'comment_author.'" width="40" height="40" />';

}

?>

with this:

As simple as that :D
