Using JAIL in ExpressionEngine
Aaron Gustafson snapped together a nice plugin to easily implement the jQuery Asynchronous Image Loader (JAIL) in your EE templates. JAIL is a “jQuery plugin that lazy load images making your page load faster.”
Aaron’s JAIL plugin (available for free on Github) is a simple tag pair that “will hunt for any image elements inside the tag pair and convert them to use the JAIL markup pattern.”
