Some people think the internet is the wild west. Not true. Here is a great primer on copyright protection as it applies to our modern age.
The take-away from the article is this passage:
"Litigation is expensive. People concerned about, say, the nuances of fair use must not become so entangled in legal details that they forget that anything generating income or interfering with another's potential income dramatically increases the chance of suit.
The most compelling questions are: (1) Is a proposed use of another's work likely to offend, and (2) Are expected benefits worth the bother and possible cost to resolve a dispute?
Why not ask? Only if the owner says "no" does the second question need to be addressed."
