This is purposeful, for backwards compatibility reasons: Lots of web pages have photos with incorrect EXIF information embedded and rely on browsers not supporting EXIF (which was true of browsers until recently) to render the image correctly.

While the default behavior has to handle the backwards compatibility issue, sites that think they have correct EXIF information can opt in to applying it to images by styling the images with "image-orientation: from-image"; you should ask flickr to do that.

Obviously users can do the same thing via a user stylesheet if they want to apply this across the board and don't care about the compat impact.
