 Lazysizes is built upon the Responsive image standard and extends it with additional functionality. For full cross browser responsive image support you must use either a full polyfill like [picturefill](https://github.com/scottjehl/picturefill) or use the extreme lightweight partial [respimg polyfill plugin](plugins/respimg) or the [responsive image on demand plugin](plugins/rias). Alternatively you can simply define a fallback src via the ``data-src`` attribute. If you want to learn more about the responsive image syntax read "[The anatomy of responsive images](https://jakearchibald.com/2015/anatomy-of-responsive-images/)".

 The ``srcset`` attribute with the *w* descriptor and ``sizes`` attribute automatically also includes high DPI images. But each image has a different optimal pixel density, which might be lower (for example 1.5x) than the pixel density of your device (2x or 3x). This information is unknown to the browser and therefore can't be optimized for. The [lazySizes optimumx extension](plugins/optimumx) gives you more control to trade between perceived quality vs. perceived performance.
