Prisoner of War Photos
The National Archives have high resolution images from the German Record Cards of British Prisoners of War (WO 416 files) that they have almost completed digitising and are searchable for free on their website. They still have to add surnames commencing N-Z.
The regrettable thing is that what you will find is only a transcript of the card and no photo. To get the photo you will have to pay. Basically they charge £40 + vat for 20 photos with further restrictions such as resolution below 72 dpi and watermarking to prevent misuse. To date I have added pages on around 750 commando prisoners of war with many more coming. As such we will not be able to add these photos to those pages in our Archive. We ourselves make no charge for our content.
