In the latest days I’ve been working on websites performance optimization and I realized that there is no way to take advantage of the progressive JPEG image format on websites if you’re using jQuery_lazyload. So after sending a pull request to its author, I decided to write my own lazy load, which turned out to be better, because:

  • it’s 6x faster
  • it allows you to lazy load responsive images
  • it doesn’t depend on jQuery
  • it best supports the progressive JPEG format
