A jQuery lazy-loading plugin allowing developers to improve a crowded page's speed by loading only what's visible on the screen
To implement the plugin, just tell it what to refrain from displaying at page load.
Screw will let the rest of the page load normally, and load the selected elements only when they come in the user's view as he scrolls down navigating a page.
Screw is recommended for vertically long Web pages, pages with lots of images, comment fields, etc..
Multiple examples are included with the download package.
