 Using Imagick's getImageOrientation is probably preferable to using
 exif_read_data, because exif_read_data can throw an error for some jpegs
 depending on how they have been modified in the past. getImageOrientation
 seemed to be more reliable and does the logic of finding the orientation
 from the exif data itself.

 However, getImageOrientation will return the same orientation after an
 image has been rotated, so you would still have to remove the orientation
 or set it to 1 after you rotate it. Unfortunately, Imagick doesn't adjust
 the orientation when you rotate it like GD does.

 Thought that might be helpful since I ran into this while trying to fix
 orientations on upload. I don't have any examples of the images this
 failed on anymore, but just something you might want to consider.
