IMO, the forum rules are clear as regards posting PCNs: 'leave in the VRM'.
We wouldn't know whether what you've posted represents the totality of their photo evidence because you won't allow us to access this.
But if what you've posted is the total of their evidence and if you assert with evidence (to the standard required at adjudication) that the necessary markings were not clearly displayed in the immediate vicinity of your vehicle, then go ahead.
