Breach of copyright! - photographs

[Brian]

Hi guys

Not having a legal mind, nor being particularly bright - could someone sum this all up in a nutshell, in plain, simple English, please?

What is one allowed to do and what is one not supposed to do? What can one copy for publication - prints/quotes/extracts?

I have to admit that I have been loaned prints in the past - and used them - only realising later that they were from/or are in the IWM collection, or FAA collection. Having said that, I am also aware that some of the photos I have used were donated to these collections, and those in the AWM collection, by my contacts! I have personally donated a picture to one of the above - for which others now have to pay a fee!

Happy Christmas to one and all

Brian
