fix_iphone_picture_orientation 0.0.1

Convert iPhone images to have a useful Orientation tag value and be internally correctly oriented. The iPhone has used the EXIF tag Orientation to store the actual orientation of the camera. A lot of programs and libraries don't seem to understand this, especially online photo galleries such as Flickr and Gallery. This program will modify the image to rotate it internally according to the iPhone's orientation value, and then set the EXIF orientation tag to "Horizontal (normal)" thus removing the confusion.
