Looks to me, when I enlarge the photos, that both posted upside down.
As David mentioned, several have had problems with photos rotated when posting directly from a phone. I looked into the file internals and found a clue then did some tests and found that I could replicate this problem if I used the "Attach files" control at the bottom of a message:
View attachment 83565
However, at least in those cases, the problem went away when I used the "Insert image" control at the top of the message:
View attachment 83566
You might try this and see if it works. You can Edit your message, use "Insert image" on both, check the results, then delete the originals (or the new uploads if it didn't work) by clicking on the little trashcan icon in the thumbnails below the message.
BTW, another quicker way I insert images when using one of my computers is copy/paste - click on the image or name in the Win10 File Explorer, Ctrl-C to copy, put the cursor where I want picture in the message and use Ctrl-V to paste. (iPad uses Cmd instead of Ctrl).
This will put the photo in the message body at a large (or forum maximum) size. I then click on the image and drag one of the blue corner boxes to reduce the image size as I want. This makes it easier to add text above and below, and put several small images beside each other. The viewer can always click on the reduced size image to view the larger size.
