Disable WEBP for specific images?

I’m assuming (perhaps incorrectly) that you aren’t using our premium Easy IO CDN, in which case, the best way to achieve what you are wanting is to append the files with the query parameter “type=original”. So, on the href link for the image, you would add ?type=original

For reference, someone did make a request to add a function to the plugin to do something more with this, but there hasn’t been much interest. I would recommend adding your vote: https://feedback.ewww.io/p/add-links-to-download-original-source-image

There isn’t anything built-in to exclude WebP for logged-in users, no.
