If you don't actually _do_ anything based on device-pixel-ratio besides ramping up the dimensions you could just leave dpr out and let the useragent figure out if it wants pick a higher res image: <img src="/path/to/image-200-300.jpg" width="200" height="300" srcoptions="/path/to/image-{width}-{height}.{format}; 200x300, 400x600, 800x1200; webp, jpg"/> For sure srcoptions caters for automation/systematic naming. I don't think that is a bad thing :) On Sun, Jan 26, 2014 at 4:48 AM, Fred Andrews <fredandw@live.com> wrote: > > > > Date: Sat, 25 Jan 2014 18:21:59 +0100 > > From: rasmusfl0e@gmail.com > ... > > Device-pixel-ratio can be quite relevant to include in urls; with an 2x > > image compression artifacts in lossy formats (jpg, webp) are less visible > > which in turn means you can crank up compression without losing visible > > quality while getting an image that'll weigh roughly the same as the > > equivalent 1x image.
