LazyImages Plugin

VERY simple image lazy-loader using node-scroll-info for positional information.

Usage

This plugin is designed to be plugged-into a Y.Node instance.

Y.one(".images").plug(Y.Plugins.LazyImages);

As the user scrolls the plugged node,images that have a data-src value will have that converted to their src value, causing them to be loaded.

You can configure the distance from the viewport to preload nodes by setting the plugin's distance attribute. The default is 100px.

Example

YUI().use("plugin-lazy-images", function(Y) {
    Y.one("body").plug(Y.Plugins.LazyImages);
});

See http://jsbin.com/wumu/2 for a live example.
