You could always paint a great big black moustache and glasses on the photo and republish :>)
Actually - I was taking some photos at a dance this weekend, and one person in a set did a very fine impersonation of someone swatting a particularly nasty insect away, while yelling "Go Away, Go Away". I took that as a request for not being included in any published photos - although I actually wasn't taking a photo of that person at all :>) A quiet "I would rather not have my photo published in any way" after the dance would probably have made me more impressed and the person would not have been on the receiving end of my: "Ooooh I just stood in something nasty" looks :>) :>) I'm not sure that the person actually saw that look anyway.

I'm very behind with my Strathspey messages again, so apologies if someone has already said this. I think you have to have parental permission to publish photos of children, but I would agree with Pia as far as photos of adults goes.
