Because the board does not adjust the pictures
If the picture shows sideways then it was taken that way and never turned and re-saved in a real photo program.
In windows you can turn the display of a photo BUT it does not save it to the photo file. Just in the windows display options
Appreciate the attempt but I'm still struggling.
I'll upload screen shots from;
The thread I mention (posted sideways)
From Apple "Preview"
From Apple "Photos"
From Apple "iPhoto"
All programs open this image in it proper orientation with the exception of the uploaded image within the thread.
