Handy script! But I noticed that it screws responsive images using srcset and sizes because it ignores the sizes attribute. This leads to the largest source being loaded. Works fine when the sizesvalue is added before applying the srcset to the <img> element created.

This doesn't seem to work in IE11 ? Can you replicate ?
