    1111Another (big?) drawback of using JS is that replacing the images at DOM ready leaves the screen "imageless" for couple of seconds. What happens is the low-rez images start to load together with the html, at DOM ready all half-loaded low-rez images are replaced with the high-rez. That makes the browser send another set of requests for them before the requests for the low-rez images have completed. So now we have double the number of image requests.
