+EXIF Orientation-flag example images
+====================================
+
+Example images using each of the EXIF orientation flags (0-to-8), in both landscape and portrait orientations.
+
+[See here](http://www.daveperrett.com/articles/2012/07/28/exif-orientation-handling-is-a-ghetto/) for more information.
+
+
+Generating your own images
+--------------------------
+
+If you would like to generate test images based on your own photos, you can use the `generate.rb` script included in the `generator` folder.
+
+The instructions below assume you are running on macOS - if not, you will need to install the Ghostscript fonts (`brew install gs`) some other way.
+
+To install the dependencies:
+
+```
+> brew install gs exiftool imagemagick@6
+> cd generator
+> gem install bundler
+> bundle install
+```
+
+To generate test images:
+
+```
+> cd generator
+> ./generate.rb path/to/image.jpg
+```
+
+This will create images `image_0.jpg` through to `image_8.jpg`.
+
+
+Re-generating sample images
+---------------------------
+
+Simply run `make` to regenerate the included sample images. This will download random portrait and landscape orientation images from [unsplash.com](https://unsplash.com/) and generate sample images for each of them.
+
+Generating these images depends on having the generator dependencies installed - see the *Generating your own images* section for instructions on installing dependencies.
+
+
+Credits
+-------
+
+* The sample landscape image is by [Pierre Bouillot](https://unsplash.com/photos/v15iOM6pWgI).
+* The sample portrait image is by [John Salvino](https://unsplash.com/photos/1PPpwrTNkJI).
+
+
+Change history
+--------------
+
+* **Version 2.0.0 (2017-08-05)** : Add a script to generate example images from the command line.
+* **Version 1.0.2 (2017-03-06)** : Remove Apple Copyrighted ICC profile from orientations 2-8 (thanks @mans0954!).
+* **Version 1.0.1 (2013-03-10)** : Add MIT license and some contact details.
+* **Version 1.0.0 (2012-07-28)** : 1.0 release.
