+Additionally, WebRSize supports a `devicepixelratio` (or `dpr`) query string parameter.  This setting will automatically adjust both the size and quality settings for the target client.  Using `srcset`, you can configure images with the same logical (CSS) size and have WebRSize take care of the rest.  In this example, a retina device will receive a 200px wide image with a lower jpeg quality/subsampling to compensate and keep file sizes reasonable.
