I was wondering the same thing. From the image-orientation spec: "It
applies only to content images (e.g. replaced elements and generated
content), not decorative images (such as background-image)."
So this property apparently has a considerably larger scope than just
correcting the orientation of images from files, which I guess explains why
it is in CSS.
