# 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.
