Question

I was browsing around the web and I saw something I’ve never seen before.
on this site:
http://blogof.francescomugnai.com/2009/04/mega-roundup-of-geektool-scripts-inspiration-gallery/

When you navigate down the page, the images only load when they are in the visible portion of the browser.
I have never seen this before and was wondering if anyone else has and how exactly one would do it.

I’m guessing this is some sort of WordPress plugin (that’s what he’s using) but I’m not sure.
Is it javascript? Are they actually loading on page load but just become visible later for a “snazzy” effect or is this actually useful for quicker page load times?

Answer 1

LazyLoad is no longer available according to the website. Apparently the code no longer works on new browsers and the author doesn’t have time to update it.

The “appear” plug in is working well for me.

http://plugins.jquery.com/appear/

It allows you to specify a callback function for an element. The callback function is called when the element appears into view. From the site:

$('#foo').appear(function() {
  $(this).text('Hello world');
});
