You should keep in mind that the loading behaviour changes wildly from browser to browser.
Chrome loads images that are a long distance out of the viewport. Native lazy loading wouldn't even kick in here on short pages.
Firefox loads images only if they are in the viewport, leading to visible loading times for the user as she scrolls.
As of now, there's no way to control that behaviour.
