add maxdpr option
<!-- if you have 3dpr choose logo3x.png -->
<img src="logo.png" srcset="logo2x.png 200w, logo3x.png 300w" sizes="100px" />
<!--
if you have 3dpr and sizes computes to 100px choose img2.jpg
but if you have 2dpr and sizes computes to 150px take img3.jpg
-->
<img src="img.jpg" srcset="img2.jpg 200w, img3.jpg 300w" maxdpr="2" sizes="100px" />
