I think your question has been adequately answered by others, shellinch. However, I am interested to understand why you (or whoever told you) believe that you cannot have your face photographed.
One of the strongest forms of evidence in court where identification is an issue is photographic evidence. In relation to allegations of speeding which have been detected by automatic camera, the police have to ask the registered keeper of the vehicle who was driving at the time of the alleged offence. One useful loophole which has been successfully exploited by some defendants (and their advocates) is that they �cannot remember�. If this can be successfully shown in court, the prosecution cannot proceed.
Advances in technology have now made available equipment which can provide photographs, taken from the front of a vehicle, which are good enough to provide evidence of identification of the driver. Your belief that such photographs cannot be taken seems to be part of the general confusion into which people have been led by inappropriate talk of things such as Human Rights and data protection legislation and this often overrides plain common sense. Any thoughts?
Also, beware of the use of the term �appeal�. You have no right of appeal until you have been convicted. If you accept a fixed penalty offer that is the end of the matter (you pay a �60 penalty and get 3 points). If you wish to have the matter heard in court you have two options when you get there. You can plead guilty but offer mitigation. In this case you will be convicted and sentenced. Or you can plead not guilty, will face a trial, and if found guilty you will be convicted and sentenced. Only after a conviction has been registered can you appeal against either the conviction (if you have been found guilty at trial) or against the sentence imposed.
