I wanted to load images on my site based on device to save bandwidth, However in this query How to avoid request of all images used for different devices using media query?

some one suggested to use src set or zurb. When I analyzed both it comes out that both loads all images irrespective of device consuming bandwidth defeating the very purpose of saving bandwidth and faster page load.

Can some one suggest me, which way I can only load images that is required for specific device and avoid loading all images when page loads?

Thank you.
