Eric Portis, on how to properly optimize the use of different image resolutions across varying display sizes on the web:
Sixty-two percent of the weight of the web is images, and we’re serving more image bytes every day. That would be peachy if all of those bytes were being put to good use. But on small or low-resolution screens, most of that data is waste.
Much to digest here, set aside some time to really dive into it.
