Fine, except that he wants the <img> tag repeated the appropriate 
number of times. Try putting the tag into the dtml-var statement 
and you get something along the lines of (untested):

  <dtml-var "('<img src=%sstart.gif%s height=15 width=15>' % 
(_.chr(34), _.chr(34))) * movie_rating">

at which point the dtml-in starts to look more appealing.

Of course if you rename star.gif as star_gif you could try:
 <dtml-var "start_gif.tag() * movie_rating">
which has a certain neatness.
