Screw, a word I re-coined from scroll + view, is a jQuery plugin which loads HTML as a user scrolls the webpage. Screw will help you save bandwidth by only loading content as it is scrolled into view. Screw can also be used to create continuously scrolling, bottomless pages where content is appended to the bottom as the user scrolls.
jQuery.Screw to load images when the image is in the viewport. Any images which are positioned inside the viewport when the webpage loads are loaded immediately. Images positioned below the viewport are not loaded until each image is scrolled into view. To prevent an image from loading immediately when the webpage loads, you must provide sufficient padding or additional content so the image is not inside the viewport.
