Photos taken with mobile phone in portrait mode not correctly shown in the backend

[Gideon So]

Hi All,

I found a problem that if I take a picture with my mobile phone in portrait mode and then upload to a PorcessWire site, the photo is not display correctly in the backend. It is rotated 90 degree anti-clockwise and the thumbnail is up-side-down. You can see it in the attached image.

Any clues how to fix it??
