If it had been shown to the public - it would have been dismissed as photoshopped by some sceptics - and Mr Edmonds would have been accused of being yet another person who was party to this massive conspiracy.
While it remains undisclosed sceptics can convince themselves that it doesn't exist and Mr Edmonds is lying about it - because he is party to this massive conspiracy.
So damned if he does and damned if he doesn't imo.
This all beings us back to the question of the paucity of photographs of Madeleine that week.
Leaving aside for a moment the two very controversial photos - the 'Last Photo' and the 'Tennis Balls' photo, which miraculously seems to have been taken on two different days by two different people - what are we left with? -
just three, all obviously taken on the late Saturday afternoon just after they arrived in Praia da Luz.
Another matter to put into the mix regarding the photographs is that Gerry and Kate McCann didn't allow the PJ to look at their original photographs.
No, they preferred the route of summoning up their cousin Michael Wright from Skipton and no less a person than the Head of Risk for one of the world's leading - and most controversial and notorious - PR agencies, Alex Woolfall of Bell Pottinger.
To do what?
To view, select, delete, amend, omit and crop all their photographs on their SD card(s), and put what was left of them on to two CDs, handing them into the PJ on Wednesday 9 May. The result was the useless 'grey-scale' images we see in the PJ files.
And why exactly was the Head of Risk for Bell Pottinger out in Praia da Luz on Friday 4 May anyway? Madeleine could have been found alive and well as he was flying out from Gatwick to Faro.
Undoubtedly there is a very deep mystery about the photographs taken on that holiday
