Parallel streaming of progressive images

Cloudflare has combined progressive image rendering and HTTP/2 multiplexing technologies to create a new method that significantly improves the perceived speed of loading for progressive images, making them appear in half the time. This is achieved by sending the most important fragments of image data sooner. The end result is that images can look almost fully loaded in half the time, without adding any cost to file size or requiring additional requests. This technique takes advantage of existing web standards and is compatible with all browsers.
