Up until now, web developers had to implement it manually via JavaScript, but now Google is integrating it into its browser. Google Chrome engineering manager Addy Osmani reveals the team is hoping to ship support for lazy loading in Chrome 75. It will be enabled by default, unless told differently.
A new loading attribute for the img and iframe tags is being worked on as part of the HTML standard.
What if the browser could avoid loading these offscreen images for you? This would help content in the view-port load quicker, reduce overall network data usage and on lower-end devices, reduce memory usage. Well, I'm happy to share that this will soon be possible with the new loading attribute for images and iframes.
