The EXIF says that it was put to Adobe Photoshop CS Windows.
I have this info from Stevo's book (Faked Abduction) where we can read a lot of details on page 187 and around. Many details were already found on forums and I WISH that the old 3 Arguidos were still alive because so much searching was conducted there. we could know what camera they had, (I can't remember if Gerry & Kate had 2 different ones... I think Kate's was a Canon(?)... If you have the time to search it, all the details will be in the files (See pamalam's site http://www.gerrymccannsblogs.co.uk/ ).
It was released on the 24th May 2007, so indeed the big question is: why not give this photo to the police (and keep copies obviously) as soon as possible?! instead of using old photos.....
There is no proof of this photo being authentic but on the opposite, only clear facts that prove it's a fake!
-the fact that they put the photo through EDITION. Ok it could have been JUST to enhance it, BUT then why keep the original, why not give it to the police immediately- even if it was just to clear the doubts...
In fact PJ should have DEMANDED this original. It's so important!!! What des PJ know about this so-called proof that Maddy was there on the 3rd May? Nothing, because they never even saw the original! Why didn't they want to know in which way it was modified, since it was about the "PROOF" of Maddy being there on that crucial day?! (imo it's all to do with the deliberate sabotage of the investigation!)
There are 3 elements (at least) that prove that it's NOT a genuine!!!!:
1) the strange line between Amelie's t-shirt and arm.
2) a minuscule forgotten bit near Gerry's finger.
3) the edition marks on Maddy's skin (near her left arm, on the right when we face the photo)
- it's only small and you would need to do it by yourself, perhaps with enlarging the hi res photo a bit, someone had made a much better one on the defunct 3as forum, the marks were similar to an older photo of "Madeleine" : the patterns that left a trace on this 'Last' Photo looked like the garment that the child was wearing on that old photo! (as shown on my album link)
So to me, no, this is NOT , no way like the original, I bet that it's fabricated out of 3 photos, Maddy alone (anywhere), Gerry and/or Amelie sitting near the tile (hence the illogical black & white line), and another for a common background.
I still would like to see if "Maddy alone " matches in patterns with the mini-wall... but is that really relevant? since even if it matches, it's not even proof that it was the original, a good idea would be to work on that exif...
Cheers and you've had a brilliant idea to resurrect this topic! Cause not many people actually realise that it's 100% fake and how vital it is for this case.

Here's one that I found interesting too (thank you author - I do not know who created it):
Here is the Ocean Club pool in September 2007, with no one on:

and the other version with only "Madeleine" on (so which is the genuine photo? or is any of these authentic?):
