Cool blog pictures without copyright problems

I'm not a lawyer and you shouldn't base your decisions regarding legality on anything I tell you. But there's good information about copyright and "fair use" on these pages:

Copyright and Fair Use Overview

What is Fair Use?

--excert on Fair Use: In its most general sense, a fair use is any copying of copyrighted material done for a limited and "transformative" purpose such as to comment upon, criticize or parody a copyrighted work. Such uses can be done without permission from the copyright owner. Another way of putting this is that fair use is a defense against infringement. If your use qualifies under the definition above, and as defined more specifically later in this chapter, then your use would not be considered an illegal infringement.
