And this is exactly what yous should NOT do. It causes the entire
(large) image to load, then be resized by the browser.
It is much better to create thumbnails and send an image of the
appropriate size. Depending on the original image size, the size
difference is enormous. For instance, if the original image size is
500x500, your thumbnail may be as much as 99% smaller than the original.
