You've managed to totally misconstrue just about everything. It was Brett Collins who approached Michael Fielder in the first place as they had had previous contact when Jeremy was arrested on the Osea Road burglary charge. They wanted yet more cash for their forthcoming holiday in the South of France.
As for Colin's interest in the photographs it's possible he wished to destroy the ones made by the London photographer, which were of a pornographic nature. He was horrified when he discovered Jeremy had been trying to flog them. The others of Sheila as a 17 year-old may have been a mistake, though given Colin's artistic bent one should give him a little licence. He's certainly not the dirty old man in a mac personage you are at pains to depict.
It was Jeremy who informed Colin of the other photos. It is obvious from Colin's statements that he trusted Jeremy hence the lack of urgency in collecting the remaining slides. In fact Colin went on holiday after taking the photos and showed no urgency in arranging to collect the remaining slides. The actual events and statements of the time show that Colin had no concerns about Jeremy's plans. His claims since then that he was concerned are betrayed by his actions.
You also, by inference, believe that having had a conversation with Colin regarding the collection of pornographic pictures, in which Colin made no immediate arrangement to do so, that Jeremy then got Brett to arrange a meeting with a reporter from the Sun, who had been busy smearing him, in order to sell the, previously unknown to Colin, pictures. Jeremy, being smeared and accused with all sorts of lurid tabloid tales about his sexuality and drugs, tried to sell nude pictures to the worst offenders and it didn't occur to him that his selling of the pictures would be a bigger story than the pictures. And you believe that this is exactly what occurred.
Neglecting to take any of the photos with him to the meeting supposedly set up for this very purpose isn't a detail that troubles you either. It is pretty apparent that those who believe this lurid tale aren't troubled by detail much at all in fact. The descriptions given by Fielder are agreed by all to be fabricated by him.
It's almost as if Fielder just wanted to write a scandalous tale of murder, sex and drugs, much like the rest of his known output, and if necessary make it up. You believe because you want to, not because there is a solid case for doing so.
