The image accompanying this post is encoded with JPEG compression, a standard which, while it has been improved somewhat, has been more or less in its present form for almost two decades now. Over those two decades, images have changed their role on the web dramatically, and consequently the number and quality of images on the web have been increasing exponentially. Yet the way we make those images easy to share and transmit hasn't caught up with the times.
Increases in bandwidth, it must be said, have made the matter one of very little urgency, and it's important to admit that it takes less time to load a content-rich webpage (our front page averages 1-1.5MB) than it did to load a barebones page in the old days. But even so, it's just as true that images take up the bulk of the bandwidth and making them more efficient means making the web more efficient. It looks like Google is trying to do just that with its new WebP image format.
