So if I view that website and the picture gets downloaded into my cache. Would I be charged with child pornography?

What if someone else had pictures of naked children on their computer and claimed them to be art?

Still got me thinking, while you can always argue the exceptions some lines I would say need to be hard and fast, black and white, because once you open it up to grey - lines of acceptability and abuse can become very blurred.

As an aspiring artist myself I am of the opinion that art is NEVER worth that risk in my opinion.
