I agree about font sizes, relative all the time. But, the <div> in question
contains just one image. AFAIK it seems ok to explicitly state absolute
sizes for images so why not the <div> that contains them?

Would a better way of making an image float right be to assign it a class
and then define this in an external css  as .imageclass { float:right }
thereby avoiding any sizes on the style?
