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.
Images are the primary reason why your website loads slowly. If your blog or websites use too many images, you need to seriously think of image optimization to make your website faster. On an average, images account for around 60% of web page’s size. So, you must think of using optimized images.

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.
There are multiple jQuery plugins that allow you to lazy load images on your website. If you are using a custom HTML website, you can simply use those jQuery plugins. 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. The best way to implement lazy load images in WordPress is the use of WordPress Plugins. In this article, I am adding few plugins.

Lazy Load is another nice plugin. It was developed by Automattic, the company behind WordPress, along with TechCrunch 2011 Redesign team, and Jake Goldman (10up LLC). It uses jQuery.sonar to only load an image when it’s visible in the viewport.
In case you want to change the placeholder image, you also have option for that. But you need to edit the functions.php file to add the code for that.
