Yahoo! UI Library: ImageLoader

http://developer.yahoo.com/yui/imageloader/

The ImageLoader Utility allows you as an implementer to delay the loading of images on your web page until such a time as your user is likely to see them. This can improve your overall pageload performance by deferring the loading of some images that are not immediately visible at the time the page first renders. Because images are often the heaviest components of a given page, deferring the loading of some images can yield a marked improvement in the way the page "feels" to your user.

The ImageLoader Utility lets you determine triggers and time limits to initiate image loading. This allows you to ensure that the images are loaded before your user is likely to see them. This technique, obviously, is appropriate only for images that are not immediately visible to your user at initial page load.

Getting Started

To use the ImageLoader Utility, include the following source files in your web page with the script tag:
