This plugin name is Lazy Loder, Lazy loader delays loading of images in (long) pages. Images below the fold (far down in the page) wont be loaded before user scrolls down.Using lazy load on long pages containing heavy image content makes page feels snappier. Browser is in ready state after loading visible images. No need to wait for unknown amount of pictures to load.This plugin is very useful for those blogs which is having so many images and taking so much time to load.
