Ok, I think I will just post an answer since I figure it out :)
Find the function function post_meta_who($post, $class){} in qa-theme-base.php and add this:
if (isset($post['avatar'])) {
if (isset($prefix))
$this->output($prefix);
$this->output('<SPAN CLASS="'.$class.'-avatar">', $post['avatar'], '</SPAN>');
}
If you don't want the avatar hanging out at the left side, then just comment what's in this function
function post_avatar($post, $class, $prefix=null)
