Lossless rotation is only possible when the image dimensions are right (I think it's a multiple of 8 or something, but not sure off the top of my head).

Have you checked with some other images of different sizes?

Thanks for the quick reply
Have just tried with some photos and they rotate lossless
Size 3648x2736x24 all divide by 8 OK
Some scanned images get compressed
Size 2472x3504x24 all divide by 8 OK
As long as the photos rotate lossless
