[Plugin: User Photo] Display user photo in Comments and in users page ( author page )

I cant figure this out!
i added wp-gravatars and that is working pretty well.
I installed User photo, and i can upload photos to each users profile.

But i am not understanding where i am to put the code in to have these pictures show up in my users / author page. or in my comments page.

i went to my comments.php and searched through it for multiple things.

I am just not sure what code i am supposed to replace. PLEASE HELP!
