The image is displayed in the wrong direction

Images taken from iphone in particular and mobile devices in general when put into the computer will display the wrong dimension

Cause: On mobile devices, in order to display the correct image when the user holds the phone vertically or horizontally to take a photo, the device has changed the orientation attribute (a number) of the image.

1 No rotation
3 Rotate 180 degrees
6 Turn 90 degrees clockwise
8 Rotate counterclockwise 90 degrees
NULL No value exists

How to fix: have to write a function that uses the orientation parameter to rotate the image correctly
