bbPress avatars not showing

I’m running bbpress with buddypress.

If you look at a topic thread on my site you’ll notice that there’s no avatars showing.

I figured out that the place where the code should exist is in /wp-content/plugins/bbpress/bbp-themes/bbp-twentyten/bbpress/loop-single-reply.php so I stuck a message that says “avatar should go here”. Here’s the code from that page:

But what do I need to put there so the avatar actually shows? Please advise. Thanks in advance!
