Re: "My images are all upside down"
#2What is the case when the photos are taken from a vertically up position? What orientation does it take? For eg: https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-ash3/54392...
Just curious. I'm sure many food photographers will try that position too.

#3There are a lot of sites that throw away the EXIF orientation tag when resizing photos. It's very obvious now that you can upload directly from the iPhone.

I don't have iPhone, but almost every phone uses same orientation for photo as for GUI to avoid confusion. Orientation for GUI is usually changed with some hysteresis and other filtering, so probably answer is "The same orientation as it was before rotating in this position".

#5What puzzles me is that Windows XP up to Windows 7 built-in picture viewer does not support proper orientation of iPhone photos with the original EXIF metadata in place.
Picasa (on Windows) handles that perfectly, as well as (obviously) all apps in OS X.
What the hell Microsoft? Is this a political thing or is there a valid technical reason?

#6“Because your crop and scale function ignores and drops the EXIF orientation tag.”

The EXIF orientation tag encodes all orientations: http://www.impulseadventure.com/photo/exif-orientation.html

#8What the hell? Why is there an orientation tag at all? Why isn't the picture just rotated by the device that takes it?
Re: "My images are all upside down"
#9Had this same issue with a service that consumes pictures from iOS/Android/BlackBerry. They all seem to handle it in different ways. I added a similar EXIF check and a quick rotation when necessary. I should have written a blog post about it. :)

Because lossless rotation is fairly expensive computationally so digital cameras have been leaving that job to a computer.
