I just went through the asme struggle, I almost gave up and moved underground. Kidding, but it is extremely frustrating. Best advice I received is take a screen capture of it and upload THAT version of the picture. Worked for me
Off the phone, I go to edit mode, crop as desired and hit save. Once saved as we wish to see it, it transfers to the HuntTalk forum correctly oriented.
When working on a Windows 10 desktop, it seems extra important to "save" the changes, as the changes are shown, but for me have reverted to the original orientation/size if I didn't "save" in W10.
I've been known to help other posters rotate their wonky pics from time to time. I screenshot with the iPad, edit, rotate, save and repost.
