So this is still in very early plan, but recently I plan to have a youtube channel dedicate to zoos and animals. As I don't have a lot of photos myself, I would like to use some media on this site for showing/introducing. Is it possible and legal to use photos in this site for it? I will state the name of the zoochatter and the zoochat website if it's ok.
You should contact each user directly and explicitly ask for their permission for you to use any photo you want to include. To do anything else would be a breach of copyright.
