That was puzzling -- I tried it myself with the test image Brion was using in
the unit tests. Orientation is  270, and yet the image remains unrotated:

     http://www.flickr.com/photos/brevity/6221434141/meta/in/photostream/

This is a guess, but the other image uses the Canon EXIF Tag "Auto Rotate".

     http://www.flickr.com/photos/igorgm/6073292209/meta/in/photostream/

...which my usual EXIF parsing tool (exiv2) can't even read or write, so that's
hard to test.

Maybe Flickr decided that Orientation was unreliable, but maybe Canon's
AutoRotate is. I'll ask.
