Images rotated 90° #119

I had some of my images rotated 90°. I didn't notice any logic behind which images get rotated and which didn't, but I'll just say that all of the ones that did rotate had height>width.

It is possible that some images only use EXIF to rotate an image and that is possibly not supported. This should be fixed in code (reading the EXIF information and rotating the image accordingly or reapplying the EXIF data on export). A workaround is to just apply the rotation without EXIF.
