how do I add
.webpto the upload function so users can upload this type of image?
I've implemented WebP-support for the upload feature and opened the pull request (PR) #623 for it. In my first tests the enhancement worked flawless as described in the description of the PR. I will perform a few further tests and try to make it ready for the next release.
