A good specific way to use responsive images is when you setup a site that gets updated by the client. You want to control the way the image that they upload gets shown. Enter, responsive images. You have to have it respond when they upload all ranges of sizes. And you have to have it conform to your template. Otherwise, you’d just do it yourself, right?

Ok,add this:

img {
	max-width: 100%;
	height: auto;
}

Viola!
