How were they taken? Camera Phone? Was it up and down?
That's the only time that I have seen pics post sideways like that, Actually a regular camera will do the same thing. If you did in fact take pics on a camera phone or a camera up and down, to me the question would be why they showed correctly on your computer without you having to rotate them.
I'm now! lol
I'm just as confused as you Paul. I took em with my iPhone in the normal upright position. I even checked em once I put em on the puter to make sure they didn't need to be rotated. The rest is SC history
