Note from 8 October 2021

Once your image CDN is (correctly) set up, support for any new lighter/faster image format is like infinite ROI: "much lighter images" divided by "zero additional cost". 🥰

It could even cost you less, if you pay based on bandwidth… 🎉

  1. Do you know good tutorials and/or examples about dealing with responsive images that are fluid horizontaly, but with a fixed height?

    Using object-fit: cover; in the CSS is easy, but how can we prevent loading many pixels that will be hidden, without using too many <source> in a <picture>?
