  # small med and x-large correspond roughly to amazon sm, med and lg. 
  # large corresponds roughly to google medium. Just one dimension to
  # prevent disproportionate scaling. We use CSS so we can set maximums
  # in BOTH dimensions but let aspect ratio remain the same. We put it
  # inline so HTML Snippet API clients get images constrained to reasonable
  # sizes without extra CSS. IE6 won't do max-height/max-width, sorry IE6, no
  # way to accomodate you (trying to put a width and a max-width triggers
  # weird IE8 bugs!). Best we can do.
  #
  # generally the 'max-height' is our operative maximum for ordinary ratios,
  # but we let the width be more than the height for weird ratio'd covers
  # that are wider than square.
