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
