Well, that's what I was saying all along: freebies.  I knew better than to try selling them.  That would be a blatant violation of copyright, and I have too much respect for intellectual/artistic property to do that.  I just wasn't sure about freebies.  I had every intention of crediting Disney, too, but I doubt that makes a difference. 

My understanding of copyright law has always been that, as long as proper credit is given, violation begins only when money is made.  I guess I need to re-evaluate my understanding a little.
