Netlify Image CDN

This is an awesome new feature for Netlify!

With Netlify Image CDN, you can transform images on demand without impacting build times. Netlify Image CDN also handles content negotiation to use the most efficient image format for the requesting client. Optimizing the size and format of your images improves both the runtime performance and reliability of your site. Transformations are integrated natively into the CDN so that repeated requests leverage layers of caching for improved performance.

I asked a few questions on Netlify forum.

    Most mentions of the magical CSS object-fit: cover; in development tutorials should be accompanied by a warning: in most situations, it means the browser will download an image that is larger than required (at least in one direction), and optimization on the server side could be a better option.
