Thanks guys, that's interesting and lalverson, yes, that's what I meant by commercial use. When I was living in Australia, I used a couple of my own creations for a couple of magazine ads but I don't buy magazines here (the US) so if they were used that way I'd never see them anyway. I was just curious, so thanks for your input.
