Image lazy loader echo.js
Lazy-loading works by only loading the assets needed when the elements ‘would’ be in view, which it’ll get from the server for you upon request, which is automated by simply changing the image src attribute. This is also an asynchronous process which also benefits us.
It helps speed up the initial page loading because not all image are loaded. As you scroll, images that come into view are loaded automatically. Very useful for image intensive page.
