checks out for me, just spot checked this image https://github.com/ianare/exif-samples/blob/master/jpg/Canon.... I loaded as an unpacked extension, works great so far.

Looks good too for imgur which typically has no metadata on the images https://imgur.com/i2iHgAI https://i.imgur.com/i2iHgAI.jpeg

Thank you for this useful extension.
