the point of doing scaling on the server side is to reduce load times. However
when the image is only being scaled by a small ammount and the original is line

the url the reduced image inlined in the page is nearly 4 times the size of the
it would seem sensible to check if the version scaled on the server side really
was smaller than the original before deciding which version to send.
