I'm curious to know my rights in the following matter.

I have images of Vanessa Hudgens nude on a site of mine. Yesterday my server provider receives a DCMA notice. In summary they say I have to take them down or I'll be taken to court.

I live in Canada, I am hotlinking the images from a image host in the UK, and my server is in the USA. Neither Canada nor the UK have DCMA, I believe.

What can happen? Can legal action be taken against me? Can my server be shutdown?

Thanks
