from time to time, there is a really nicely design graphic file or a
nice looking photo, but when it is displayed with a smaller size on IE
or Firefox, the browsers, trying to save time, will make a coarse
resize shrinkage of the original image... and it looks pretty bad. is
there a way to tell the browser by HTML / CSS / browser settings, to
take more time to refine it?

especially, when the page is loaded and the 2GHz Core 2 Duo and Quad
core is sitting there doing close to nothing... why not spend 1/1000
second to make it look better?
