My b2evolution Version: 3.3.1

We have this code for display the author's avatar for each post:

$Item->author( array(
'link_text' => 'avatar',
'link_rel' => 'nofollow',
'thumb_size' => 'crop-64x64',
'thumb_class' => 'avatar',
) );

Do we have a code like that for each comment to display avatar of users who left a comment for a post?

for example:
$Comment->author( array(
'link_text' => 'avatar',
'link_rel' => 'nofollow',
'thumb_size' => 'crop-64x64',
'thumb_class' => 'avatar',
) );
