I’ve just generated a webp version of every image file I’ve ever uploaded to this site, with the intent to add a redirect for browsers which support the format – that should be most, nowadays. I haven’t done the redirect yet, but I’ll turn that on later.
I also took the opportunity to fix a whole bunch of missing thumbnails and missing sizes for my images. A previous mishap on my part meant there were a lot of these missing. WP-CLI didn’t seem to work for me, but there’s an easy (although repetitive and boring) way to do this through the library:
* Open the image
* Click “Edit Image”
* Flip the image, then flip it again
* Save
So hopefully that’s any broken images fixed, and soon, speedier and more optimised versions will be served.
