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. This is opposite of image preloading.

Using Lazy loader 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.

There are options for control maniacs who need to fine-tune. You can set threshold on how close to the edge image should come before it is loaded. You can also set placeholder image and custom event to trigger loading. You can check out the demo with FadeIn Effect enabled.
