Access image EXIF info on mobile

[Alan]

I have made a test stack to access EXIF information on both Android and iOS and submitted it under bug 21322:

There is a problem (at least on the simulator) that causes a crash currently, hence my bug report. Hopefully the sample stack is useful for others and if anyone could test it on an iOS (or Android) device could you please comment on the bug report as to success or failure? Thanks!

cheers
