I have a site here.
For example https://clever-khorana-bddb4f.netlify.app/images/banner-bw-lion_3x2_1800webp should be available.
It produces optimized images if required but has cached versions in the repo so only new files are produced.
In this version image processing should be skipped entirely and the files copied. I’m getting all of the jpg but none of the webp.
On a previous attempt with the site it did serve webp or I may have guessed there was a mime problem?
