putting this out there in several forums so I can make a decision. I have looked it up but no matter how much I try to find out I never get a definitive answer so I need your help please. I went to a paid event, the royal Lancashire show to be precise, and I was wondering whether I am allowed to take images there? If it is a paid entry does that make it private? And if I can take images, am I allowed to show them online on Flickr as long as I don't get paid for them?
I mainly like to take street photography images and although I am pretty sure it is legal to do that without permission in a public place, I am not sure whether it is legal in a place like that. I also am not sure whether it is legal to put the images online on a website like Flickr without permission. Please tell me the best you can as it would really help me as I really want to just show these lovely images I have taken without being arrested
thank you in advance 

I think I feel a little safer to put my street photography online now. At least without selling them. Do you think I should put a message in the description saying I will happily delete an image if the image is of them and they want me to? I think I will in fact contact the people and see what they say about it for those images taken at that particular event to be sure. Maybe they will want to buy them. Here's hoping nothing happens
