The image you’re about to see is not residing on my server; it’s being served by ReSrc.it – a new cloud-based service which will actively deliver the optimum-sized image for your device. Don’t believe me? resize the browser window (so that the image size is reduced); reload the page and check out the source. you should be getting a new image every time the window is resized!
This is a massive leap forward for responsive design; it means that the right image, at the right resolution, at the right time can be delivered to your device. ISPs and Network providers are going to love this (as it saves on bandwidth); Web designers, photographers, content producers and anyone who works with images online have been crying out for this sort of a service since the whole ‘responsive web’ thing started.
