Oh, fer heaven's sake, may copyright law be repealed soon. Until then, here are a few photos I took myself; they are thoroughly, entirely, completely, utterly copyright-free, and may be used for any purpose, of any kid whatsoever, without asking for any permission:
House and garden, near Soesterberg, The Netherlands:
Autumn in the Netherlands:
Protea flower head, South Africa:
Swan reflected, South Africa:
I'll look around in my collection to see if I can find any more. Unfortunately all from South Africa, where I live, or the Netherlands, where I spent two years around 2000. So not as much variety, I fear!
