Echo is a standalone JavaScript lazy-loading image tool. Echo is fast and uses HTML5 data-* attributes. Echo works in IE8+. Echo.js is probably as simple as image lazy loading gets, it’s less than 1KB minified and is library agnostic (no jQuery/Zepto/other).
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.
Requirements: JavaScript Framework
