Images are a crucial part of every website and application nowadays. Whether it be marketing banners, product images, or logos, it is impossible to imagine a website without images. But large images have a bad impact on the performance of the page because they slow down your page load speed. So, we can use Lazy Loading Images as the solution to this problem.

Lazy Loading Images is a set of techniques in web and application development that defer the loading of images on a page to a later point in time, when those images are needed, instead of loading them up front. So, there are many ways to utilize Lazy Load Images in your web applications. Bartosz Dominiak introduced an Image lazy load component based on Intersection API. It is a lightweight and easy-to-use Vue js component.
