Lazy Loading is the technique for loading web page content when they are needed rather than all at once. This process helps lower the download size of the web page which loads the content quickly as only a portion of the website needs to be downloaded when a user opens it for the first time.
When a user comes to your site, the site loads depending on the size of the page, the amount of content and the number of images.
Every image sends its own HTTP request that your server has to process before the user views the content.
An image heady site can take ages to load if you don’t have a super powerful hosting server. So, lazy loading is the feature that will make the images load only when the user comes to the image section.
many top quality WordPress themes come with the built-in feature of lazy loading images making the site faster. You can have a look at the MyThemeShop themes, they offer a number of amazing features to make your site load quickly.
