In short, this plugin modifies “the_content()” and the post thumbnail function by re-rendering the images with use of the SRCSET attribute. Other plugins do this for templated images, but not in the content region itself. This plugin will automatically work with any previously uploaded images as well.

Post Script Responsive Images

SRCSET responsive images on wordpress for content images.
