Sites with a ton of images can take forever to load. For every image, that’s another HTTP request, and more time your users have to wait in frustration while pages load slowly. So what’s the solution? Lazy loading. Lazy loading can significantly speed up image-heavy sites and takes no time at all to enable on your site. In a nutshell, it forces images to load only when they are “above the fold” – in other words, only images that come into view in a user’s browser will load.
