Posting pics rotate 90 degrees?

[MinnBobber]

When I post pics on many forums, they rotate 90 degrees .
How can I adjust this?
I phone XR

Thanks

They are all shot in normal I phone orientation but rotate when posted , yet some stay as they should….
In my Photo Library, they are all properly oriented.

What I've done successfully in the past when image rotation fucks with me is to rotate the image myself, save it, then rotate it back and save it again. Then upload the image and it should be oriented correctly.

@Stu
But is that for pics that are in your photo library that have rotated/ are off 90 degrees in your library?
My photo library pics are fine. Often when posting somewhere, they rotate by themselves/ show up rotated 90 degrees. But my originals are all in proper orientation….

EXIF data imbedded in pic has an orientation code
Image viewers like iphone photos app read code and adjust if different than code 1

But, EXIF data can get stripped from pic when uploading to hosts
Then image viewers no longer automatically rotate

This problem happens to me when taking iphone pics in portrait orientation
Landscape (sideways) never give me problems

My method is using "old fashioned" windows freeware FastStone
Delete all EXIF data...then the portrait pics result in wrong rotation
So, then edit, rotate and save
Now doesn't matter if host strips EXIF or not

Added (primary) bonus of deleting EXIF data -- location privacy

There are many iphone EXIF apps for around $5
Can strip away data from batches with paid options

One kludgy workaround I discovered for free, just playing around today. Sounds similar to Stu's idea. If you take a portrait photo, edit it with iphone default photos app, rotate 90 degrees, press done. Then edit it again, rotate it three more times until right side up, then press done. Now, the EXIF orientation code is defeated, and even if EXIF gets stripped, pic will appear correct
