Perhaps, there are 1750 odd Concorde photos on A.net, there would have been tens of thousands if not hundreds of thousands taken during the lifetime of that aircraft. It is a little arrogant to assume there must be A.net photos on that CD.
Perhaps there are.. I can believe that, Perhaps there are violations of other's copyright as well. Just think it is arrogant (or/and paranoid) to assume there must be unauthorised A.net photos everytime a collection comes up for sale.
If your camera sends text messages, that could explain why your photos are rubbish!
