What is exclude above fold images?
Above-fold images are the images a visitor see in your website without scrolling.
It's a good practice to exclude such images from lazy loading. This helps to improve the render time so that images are quickly visible to the user.
FlyingPress can automatically detect above fold images and exclude them from lazy loading.
Images that are excluded from lazy loading will have an attribute loading="eager". Otherwise, it will be loading="lazy".
