Image code missing in wp-review/box-templates/default.php

The featured image/thumbnail does not show up so I had a look at the code here: wp-review/box-templates/default.php. And I can’t find it so that explains why it doesn’t show up!

I thought the image was provided in the free version, or am I wrong?
If it should be, can you please provide the code?

Thanks!
