Also, when I view these portrait images in a different image viewer or open in the photoshop, they are viewed as portrait images, then the original orientations are portrait???

@Victoria

Yes exactly, that's the case. Just try to rotate the image in your computer before uploading it to K2. That's why images are corrected when you save them through Photoshop. It writes the correct metadata to the file.

Note, that you can also rotate an already uploaded image using the K2 media manager.

Thank you.
