Recent Comments Widget Avatar

Hi I don’t know if this is in the right place, if not please move to the correct place.

My problem is, I am using the dynamic sidebar function. I noticed on a few wordpress sites, that the recent comments widget has avatars/gravatars.

I would like to add them to mine, but i’m not sure how. I have search google and not been very lucky in finding results.

Here is the code i’m using for sidebar.php

<?php if ( function_exists ( dynamic_sidebar() ) ) : ?>

… regular html …

<?php dynamic_sidebar (); ?>

… regular html …

<?php endif; ?>

It would be a real big help, if anyone knows how to do this.
