There's only one photo on the council website:

I know a trick to get the CEO's notes and here they are:

This all seems rather dodgy: the CEO took no photos of the car, and usually when a PCN is handed to the driver they will take a photo showing the PCN in the driver's hand. I suspect the CEO just made up the notes and lied to you in order to avoid confrontation (to be fair I'm sure they get plenty of abuse from people who think that colourful language is remotely helpful).
I would therefore just stick to what happened:
Dear London Borough of Richmond upon Thames,
I challenge liability for PCN RT40731652 on the basis of a procedural impropriety. At the time when the PCN was issued, I was standing next to my car after it's parking had expired as I was waiting for my family to join me. The enforcement officer hadn't noticed me when he entered the ticket into his machine and I challenged him when I realised what he was doing.
The enforcement officer then said that he would cancel the ticket. He did not place the PCN on the car and he didn't hand it to me either, he kept hold of the PCN and said he would cancel it. I note there are no photos anywhere showing either my car or the PCN, the only photo shows a sign.
A notice to owner can only be served if service of a regulation 9 PCN has taken place, in the absence of a PCN being served the council has no authority to issue a notice to owner, therefore service of the notice to owner is a procedural impropriety.
Furthermore, the facts stated at (link) are untrue and did not happen. If the CEO has body worn video, I request that a copy be provided as I am confident they will confirm a PCN was not served.
Yours faithfully,
You probably won't have space to paste all that into the council website, so put it in a PDF and upload it as an attachment.
I will send you a PM with a link to the CEO's notes, that link has click counting enabled so I can track how many times it is clicked. If they don't bother to look, the click count will be zero and we'll then have another procedural impropriety as they will have failed to consider the representations and the supporting evidence, and we will then have another procedural impropriety to use at the tribunal.
Because of this,
do not click on the link I will send you, it is imperative that the click count remain at zero.
