Wrong way round pics. I have a theory. Solved see #4

and a little googling offers this:

extract

What’s happening is that when an iPhone takes a photo, the only time the orientation of the pixels of the photo are “correct” is when the camera is situated such that the home button is on the right and the orientation is landscape. In all other situations–like a portrait photo, for example–the pixels don’t get moved, but the orientation gets burned into the EXIF data of the resulting image.

In other words, there’s a secret message inside the photo that says “despite all appearances to the contrary, I’m actually a portrait photo.”

begs the question is it just iphones? I seem to think not dot dot dot

/sites/default/files/styles/ckeditor_upload/public/inline/images/

so it's a default "style" and these  allow this: see where it says "rotate"

To create or change image styles:

Choose Administration > Configuration > Media > Image styles.

Add or select a style to edit its settings.

When configuring styles you can add effects: crop, scale, resize, rotate, and desaturate (other contributed modules provide additional effects). For example, by combining effects as crop, scale, and desaturate, you can create square, grayscale thumbnails.

Save the settings.

On an iPhone or iPad all you need to do is make a small edit (such as crop or change the contrast) when the jpeg version of the photo is in the desired orientation and re-save the photo, updates the EXIF tags for compatibility with this site. No need to transfer to another platform or use any other editor not standard on the iOS platform.

linky add in here would be good:

I'll summarise this when it's all in.

My links are to that thread once you had apprised me of it. - Welcome, Anthony

so did you do a summary in the end?

I seem to think, yes IOS but not always.
