I have a bunch of images, say 100 images, in a web page, and only 10 are visible without scrolling the page. The first 90 images have a "myclass" class.
I manage all images with jquery lazy (http://jquery.eisbehr.de/lazy/), and it works perfecty if I scroll the window.
However, If I make $(".myclass").hide() before scrolling down, I see the last 10 images, which don't have the "myclass" class, bug jquery lazy doesn't "reveal" them.
Why?
Because lazyload triggers on scroll events.
$(window).scroll() (which triggers the scroll event on the window) is enough to solve the issue.
If the scrollable div is not the window object, use it instead of $(window).
