Well, that is one way to make a mess.
It's like you say, there could have been worse things to make a mess with.
Yeah. The sideway picture thing, the way I deal with it is just to edit the photo. It doesn't matter what you change; you can enhance the colours, crop it, resize it, or anything else, then save it. It puts it the right way up every time when I do that. Just edit and resave it, then upload the edited photo.
I’d forgotten that trick. Thanks for the reminder.
