public class ImageLazyLoading extends com.google.gwt.user.client.ui.Image
Image lazy loading is based on the GWT Image and provides all the functionality inside. The difference is, image urls are put into the image tag when image is in the viewport so no images are loaded by the browser, which are not visible.
