Your page will start to load all images, but it gets complex, each time the user won’t look up to every image so it is not required for you to load all images.Loading the all 40 products will take a time –
As not every customer will see all products they are interested to look up at only a few product images. So, lazy loading will display only 10 product images before going to the product page

Why is lazy loading great?
