for some reason on my computer your picture was showing up upside down. now that i am on my phone it is not. the joke is that since we are in america and Austrailia is on the other side of the world in the southern hemisphere that everything would be upside down.

The original photo might have been taken with the phone in the wrong orientation, it would have been rotated on the phone software in the metadata but sometimes the rotation is not applied when looking on a desktop computer.
