Automatically adapts your existing HTML images for mobile devices. No mark-up changes needed. Just drop it in and forget about it. Why? Because your site is being increasingly viewed on smaller, slower, low bandwidth devices. Your desktop-centric images load slowly, cause UI lag, and cost your visitors un-necessary bandwidth and money. You've implemented a responsive design in CSS, and need something to adapt your <img>'s too.
