Think about that the next time you see a photographer's website with a long "We gonna hunt you down like a dog" admonition against 'stealing' any images on it.
Of course we don't want copyright theft - and I WILL hunt them down. And I warn against the taking with a simple copyright statement. But having to have someone click an 'I accept" button at the open screen?
Yawn... most of the time the images aren't really worth taking anyway.
