Simple jQuery extension for dynamically loading images while scrolling. Intended for image-heavy websites to save bandwidth and decrease intial load time.
Include the latest version of jQuery and jQuery.loadScroll.js in the <head> of your HTML document:
<script src="jQuery.min.js"></script>
<script src="jQuery.loadScroll.js"></script>Reference the loadScroll() method and use the data-src attribute for all dynamic loading images. The data-src changes to the standard src attribute as the image(s) enter the viewport. Placeholder images are optional. See the live demo: code.nath.co/loadScroll
