Tech Notes
Lets work on picture roation and EXIF editiing.
ExifTool by Phil Harvey https://www.sno.phy.queensu.ca/~phil/exiftool/ Edits image EXIF metadata; command line utiltity
ImageMagick more attempt to edit EXIF. Good image editor. https://imagemagick.org
Gimp Another attempt to handle EXIF.
Pixillion Use Flexxi instead, this is crippleware. Bulk image resizer, preserves timestamps, allows true percetn reduction https://www.nchsoftware.com/software/

Here's a file which displays in MSPE as rotated (but which is not):
Here's another which is taken portrait, EXIF says Rotated 90 CW: If displays properly in file manager but in MSPE and Lview it appears rotated.
Here is the same file rotated in Lview:
Here is the image rotated twice in MSPE
Another batch
