Sample images all have 1 orientation flag

Thank you for your blog post, it finally put me on the right track.
Im afraid there was some mistake with sample images. They all seem to have orientation flag set 0

Just realised photoshop auto rotate image import and shows you adjusted metadata. Sorry about about this. This issue is bogus.
