[theme-reviewers] The_post_thumbnail function bug?

I apologize for the brevity:

1) Currently, the $size passed to the_post_thumbnail() must be a
*registered* image size. Passing an array currently does not work.

2) I would suggest if ( has_post_thumbnail() ) as the conditional for
determining if the current post has a post thumbnail.
