iPad photo editing probelm

[hoosiergrad02]

I've just edited over 200 photos using the internal ipad 2 photo editing options (ie crop, enhance, and redeye). I have since plugged my ipad 2 into my computer to transfer these newly edited photos over, however when I view the transferred photos on my computer it shows that no changes have been made. How can I save the newly edited photos over the originals (ie replace) so I can send them over to my computer? Thanks in advance.
