Image upload orientation data not taken into account

Subject: Insert Profil Picture
Description:
I chose a picture as my profile picture. I'm using Firefox on an android device

Results:
There was no preview picture, and when I accepted the picture, it often was orientated in apperently random directions.

I suspect this is due to rotation data on mobile not being applied?

Be aware, some browsers will auto rotate the image for you, so if you add rotation to all images, you might end up with images being rotated twice.

The 'soft' rotation in EXIF data can sometime be stripped away when manipulating images.

We strip all EXIF data in the media uploader (on save, not on load), that might explain why browsers will not autorotate it and images are sideways.

Seems we should probably call this to autorotate ourselves before stripping that data

@Hassan-Mallah: do you want to have a look at this one? It's not in the backend, it's in the media container, in //app/media

[Hassan-Mallah]

@aapeliv sure, i'll check it
