All images not shown on screen will be loaded only when the viewport (visible area of the screen) is scrolled down over them.
This is opposite of image preloading.
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.
Here are some key features of "Lazy Load":
· Customizable sensitivity
· Placeholder image
· Event to trigger loading
· Use effects: fade, slide, etc.
· Images inside container
· Delayed loading of images
