@anna, @budnitz. Just an update on "sideways-ness" (not sure if this is helpful...) but i've found that uploads from my iPhone are all sideways, all of the ones from my apple (using safari) and iPad are all correct. So it's something on the iPhone being naughty. Good news is that I've finally corrected all of my images.
I'm glad that the site seems to be taking off, happy for you guys.
