Good point, Sue.
I find that Windows 10's auto rotation using the EXIF data confuses quite a few people (and personally I would prefer if I could turn it off and just manually rotate the photos I need to using my preferred lossless rotation program). Often they look "up the right way" on the computer but as soon as they're uploaded to a website, the EXIF data typically gets stripped (and Dave intentionally does that here to protect privacy), so photos that aren't natively "upright" end up being rotated the wrong way!
