While previewing changes locally, my Hugo build would fail on unknown image format. I discovered that a bunch of images were named with file extensions that did not match their actual mime types. For some reason, that causes a failure on my setup when a Web/P image masquerades as another type.
I wrote a quick script to detect/fix them and discovered 242 misnamed images. Would a PR to fix these be welcomed? The automated fix may increase filesize, but it's a lot easier than fixing the names and then fixing all the references to the names.
Also, can we do a PR check to validate that the extension matches the actual file content?
