bLazy is a lightweight lazy loading, multi-serving image script. It’s written in JavaScript and doesn’t have any dependencies for third party libraries like jQuery.

The goal of bLazy is to help save bandwidth and server requests to your site to everything loads that much faster. (As an added bonus it saves data usage for mobile users as well.)

The loader has a sleek look and can work with almost any style of website design. The code is fairly easy to understand and install.

Here are a few reasons why you should try it:
