thanks for posting this, and yes you are right that you need to copy that file accross, otherwise it will get overwritten by updates.

You can also achieve the same result by putting

function retina_avatar ($args) {
$args['size'] = 160 ;
return $args ;
}

add_filter ('bbp_before_get_reply_author_link_parse_args', 'retina_avatar'  );

into your functions file, of course ‘As long as your CSS specifies a width of 80 (or whatever you prefer), you won’t see any change in the size of the avatar in your browser’

Thanks again for a useful post
