As I don't have any simple way to test cloud storage, I'm filing this as a bug.

1. StorageObjectWrapper should have a close() method
2. process_media/__init__.py should use the real closing() function from contextlib instead of the current dummy one.

I would also suggest to rename StorageObjectWrapper to include something about CloudFiles.

Make it so that each StorageInterface implementation has it's own submodule.

e.g.

- mediagoblin/
    - storage/
       - cloudfiles.py
       - mountstorage.py
       - basicfile.py

The tag specifies that the image is to be displayed rotated and how.

The tag is supported by:

• MediaWiki (it generates thumbnails already rotated).
• digiKam (there is an option to set Orientation after rotating an image)
• Geeqie (rotates for displaying)
• Nautilus
• Eye of GNOME
• Thunar
• exiftran (according to the man page)
