[Plugin: WP Tocuh] how to show Avatar image on post & excerpt pages?

I remember could do that using the older version of WPTouch …isn’t it the new version had disabled this function?

Just want to show avatar image (not just author’s name) in post and front (lists of excerpts) pages …. should I edit the code? how?
