Description Edward 2013-07-28 17:58:52 UTC 
JPEG images show the correct orientation in Dolphin previews, but Okular opens some images rotated 90 degrees.

Reproducible: Always

Steps to Reproduce:
1. Double-click on an image in Dolphin to open it in Okular
- Note that this only happens for some images.
Actual Results:  
Image opens rotated 90 degrees.

Expected Results:  
Image open upright as per Dolphin preview.

Example photo that opens upside-down

This photo displays correctly in Dolphin, but opens upside-down in Okular (rotated 180 degrees).
Comment 2 Edward 2013-07-28 18:10:58 UTC 
I suspect this is due to the EXIF orientation value not being used by Okular. Many cameras, including iPhone, rely on this value to indicate which way a picture ought to be displayed.
Comment 3 Albert Astals Cid 2013-07-28 21:58:02 UTC 
Right.

OTOH we open jpeg images because "it's virutally free", but tbh using okular to view jpeg images is a bit weird :D So personally I don't think I'll have time to fix this issue (there are much more pressing issues imo)
