Really enjoying your whole setup and API, but ran into a strange issue... when grabbing my list of images via API, the `url_thumbnail` is always in landscape format (300x200) – shouldn't this be based on the orientation? ie. landscape » 300x200, portrait » 200x300, square: 300x300? (or even better if those general sizes were specific to the aspect ratio of the image). Slowly learning about creating/uploading images, where of course I can customize an available version... just thought it could be helpful to implement as default.
