European Copyright Derective or EUCD, which addresses some of the same issues as the DMCA. by means of the separate Electronic Commerce Directive (ECD)
UK law on copyright property sent across the internet or kept on web servers is generally protected in a similar manner as material in other media. A person wishing to put copyright material on the internet, distribute or download material, that has been placed on the internet by others, should make sure that the correct permission is given by the owners of the rights within the material, unless exceptions of copyright apply. Naturally, you do not need permission if the owner directly states that copying is allowed, some website owners allow this,.but be sure that when doing this that you are not in breach of some else’s copyright.
The law is different in other countries so, copyright material might have been placed on the Internet in another country that would not be infringing copyright there, but it could be illegal to use (including to download) without permission from within the UK.
