Supproting browser reisze as trigger

Lazy image loader works exactly as expected. There is one problem however and I'm not sure if it's by design?

Scenario: Viewing a website in a non-maximized browser and then maximizing it.

Problem: The images that now come into view because of the added space from resizing the browser do not load until the user scrolls.

Question: Is there a way to trigger lazy image loader on browser resize the same that is upon scrolling?
