Comment (by Compute):

 What if the current theme includes this functionality? Then we would have
 2 "post-thumbnail". While it does'nt break anything I would be alot nicer
 if there was a check if this class is already represented.

 Using {{{array_unique()}}} before the
 {{{
 return apply_filters('post_class', $classes, $class, $post->ID);
 }}}

 Might be even better.

 Checking for {{{current_theme_supports()}}} would be smarter to use before
 all this and maybe put this check into the {{{has_post_thumbnail()}}} or
 {{{get_post_thumbnail_id()}}} instead of checking for this on every line
 we use thumbnails.

 Just 2 suggestions from my point of view :)
