I want to use this LazyLoad plugin for JQuery. http://www.appelsiini.net/projects/lazyload
But, they say this at the bottom of the page:
Due to webkit bug #6656 Lazy Loading wont give you any improvements in Safari. It will load all images you wanted it or not.
It seems jQuery 1.3.x breaks the plugin for IE. All images get loaded in the background even when they should not. I am working on it. In the meanwhile stay with jQuery 1.2.6.
