Fixed issue that the delete images feature also deleted webp-images that was uploaded as such, when webp-express was configured to store converted images in same folder as originals (not the default option). Also fixed conversion triggered by redirection, which broke on a few systems in a recent update, causing images in the media library not to appear. It may however still be a problem on a very few systems. In that case: Simply disable "Enable redirection to converter" and "Create webp files upon request" and submit an issue.
