I could take a photo of some celebrity and sell it to a newspaper, who then publishes the image - all without the celebrity's approval.
FlameDuck said: Yes. But it's still copyright violation, and depending on where you're taking that picture, potentially a criminal offense too.
I think you're confusing copyright with image rights, and in some countries image rights don't exist. In most countries you don't need permission to take someones picture, however, if image rights apply in your country making money from those pictures would be questionable.
