UKNeedsAPirateParty writes: The National Portrait Gallery, London has sent one of the users of Wikimedia Commons, who had uploaded a bunch of NPG website images to the Commons website a legal threat, after Wikimedia refused to remove the images of many Public Domain portraits from their website. Since NPG apparently couldn't get their way with Wikimedia, they now seem to have decided to go after an individual. Wikimedia seems to assert that due to Bridgeman v. Corel, the copyright claim over these photographs is weak at best due to lack of originality. NPG on the other hand claims that this US court decision is not relevant in the UK and also claims their database rights. This practice of claiming (copy)rights on anything and everything build around works that themselves are in the Public Domain, has been described as copyfraud, but defended by others as required to maintain the financial health of museums.
