I think the conversation regarding trademark is totally irrelevant here.
mybottleshop.com.au (my client) sell one-off individual bottles (they are not a en-mass distributor) and the bottle in the shot is literally the bottle you buy.
The manufacturer often supply their own image, but my client chooses to not use them as he is trying to NOT be just another run of the mill online store selling the same as anyone else.
My client wants to present this bottle in it's best appearance possible - the label on the back should be visible if you are looking at the back of the bottle, not from the front.
I think there is no way possible to achieve this in camera, but I was willing to put it out here in case someone can prove me wrong.
Your client can't have the impossible.
