If your blog or website containing many images, Lazy Load will be very helpful to you. It can reduce the page loading time of your site. Lazy loader is a jQuery plugin written in JavaScript. It delays loading of images in (long) web pages. Images outside of viewport (visible part of web page) wont be loaded before user scrolls to them. Using lazy load on long web pages containing many large images makes the page load faster. Browser will be in ready state after loading visible images. In some cases it can also help to reduce server load. Lazy Load is a famous plugin for wordpress blogger.
