Quill corrects the photo rotation based on exif data since iOS tends to take landscape photos and set the rotation bit when holding it in portrait mode.

Twitter changed some XSS security settings which prevents Quill from injecting JS onto the page for the inline "favorite" button. This change makes it open the "favorite" screen in a new window.

With this it is possible to post a photo note with a description, nothing
more. It doesn't move the file in the file system, just posts it from

content type and max upload size and shows the errors to the user.

If everything goes according to plan the response from the users server
is shown, together with a link with the posted photos URL.
