In browsers where an Intersection Observer is not present, your images will be loaded immediately much like standard `` elements. Conditionally delivering the [IntersectionObserver polyfill](https://github.com/w3c/IntersectionObserver/tree/master/polyfill) along with your `lazy-image`s to your users will ensure that all users experience the benefits of loading images lazily. Stay lazy, friend!
