Sorry I made a mistake, the kiss picture was taken on Aug 4th, and published on Aug 10th in Mirror(from Operation Paget Inquiry).
There was a BBC article about Diana tipped-off information to photographer Jason Fraser.
"I was given information that she was seeing Dodi and that they were in the Med. I didn't know exactly where, but I was told the name of the boat. So I discussed it with [Italian photographer] Mario Brenner who found it and got the photographs."
"After that I took over and photographed her in Porto Fino, Sardinia and the South of France...right up until Paris. I didn't go to Paris. But otherwise I was always there, wherever she went. I was the person who revealed her relationship, I don't know whether that feels good or not, but I will be remembered for it."
He didn't revealed the source name. But "sources close to Fraser say that in the final frenzied weeks of her life, he spoke to Diana nearly every day."

Ok, in this version, it was some unknown sources who made us know Diana called the photographer to take the picture.
There are another version. In a larry king interview, simmons said something:
SIMMONS: Well, I do actually believe that the version that Kate Snell tells, which she's the only one that's had access to Hasnat Khan, the heart surgeon, where she said that from the boat, Diana phoned the photographer, Jason Fraser, gave the position of where she was and then complained after the photos had been taken that they were too grainy.
She organized the whole photo shoot.
At the same time, she was phoning Hasnat Khan and his family every day from that yacht.

From this it seemed that Kate Snell was informed from Dr Khan and his family that Diana phoned the photgrapher Jason Fraser. I don't want to talk too much about this version, but it was too ridiculous. Actually I think there are only two persons who know the truth, Diana and Jason Fraser. Diana was dead, and Jason Fraser refused to disclose the source. And no one ever bother him to explain in more details.
There is an other interesting article about Mr Fraser, talking about how he was able to chase Camilla Parker Bowles in a beach in Mauritius in 2001. The sensitives of Jason Fraser to celebility was amazing. He was able to book a first-class seat just behind Camilla, though she was under a false name.
"Fraser will not reveal his source, of course, but vehemently denies that it came from someone in BA, though it is strange how well informed he is about the movements of celebrities around the world."
And there was something in the article I didn't know before:
"More pertinently, executives at the Mirror point to a St James's Palace spin -doctoring initiative which, they maintain, is aimed at presenting Camilla in a positive light. They claim that they, along with one or two other papers, often receive calls informing them that if a photographer were to be in a certain place at a certain time, they might be able to take a picture of Camilla attending, say, an opera or a private party linked to a charity.

And in 2006, Jason Fraser was sued by Mohamed al-Fayed in Frances of breaching Diana and Dodi's privacy. The case dropped without revealing the reason, and a relieved Mr Fraser said "Only Mr Fayed will know why he decided to spend such a great deal of time and money on throwing so much dirt at me."
My opinion is Jason Fraser knew wherever Diana and Dodi would go, and followed them everywhere EXCEPT TO PARIS. Good sense huhuh. He was quite different to other paparazzo. He seemed have a lot of sources giving him information, though no one ever questioned who they were. What surprised me is, such mysterious figure as Jason Fraser was, has never been mentioned in "The Operation Paget inquiry report". And he was not asked to testify in the recent inquiry either. Actually, if the source was Diana, then it is very easy to speak out, because it would not make any news, since everyone have already assumed it was Diana.
