title: ImageResize rotating a uploaded photos
body: <p>I have issue with ImageResize. Everytime when I uploaded a photo from mobile I have this photo rotated. When I checked a original upload photo looks like fine (good rotation) but after resize of a photo in script, photo was a rotated :( Any ideas ?</p>
  <p>Many thanks in advance</p>
