I don’t think there is any need to explain the importance of website’s speed optimization. I have already covered it many times in different articles. In WordPress speed optimization guide, I also explained the importance of lazy load images in WordPress.

You can use image optimization plugins on WordPress to optimize images and reduce the size without compromising the image quality. Another good thing is to add lazy load in images. If you are not sure what is Lazy load and how to implement it on your WordPress based website, keep reading.
What is lazy load of image
Lazy load of images is limiting the images loading in order to reduce the page size. In this process, the website only loads images which are inside the viewport. So, images which are not in the viewport, that will not be loaded. When you scroll the page to see the other content of the page and a new image comes in the viewport, it loads that image.
This process makes web page faster by reducing the page size and it also helps in reducing the data bill of your visitor.

If you are using WordPress, you can either use any available plugin or customize the theme to include a jQuery plugin and then edit templates according to that jQuery plugin.
