A licence for educational use for each photograph has been acquired by the education unit of the British Red Cross. This allows schools and other educational organisations to use them freely, without payment, as part of the quiz package. The licence does not extend beyond this use. This means that anyone wishing to put the images on a website, crop or edit them, or use them in any other way than for the quiz, must first contact the copyright holder and negotiate a licence for the use they require. Picture agencies take violation of licences very seriously. Some charge punitive damages for unauthorised use of copyright photographs – in some cases up to five times the standard licence fee. If you are unsure whether your proposed use is acceptable, please contact the copyright holder. The British Red Cross will be unable to assist anyone who violates the terms of the licence.
