I do post images of folks whom I know and are identifiable and who know their image may be posted on the net...not too often with shots of folk I do not know but I certainly have a few.  My understanding is that the subject of the image essentially has rights to the shot...unless released and unless a public shot of more than that one subject.  Still, I am also confused.   Not much to add to this.   Best wishes in sorting it out.

, I ask permission for any close shots before taking the shot. I have done this most always.  Most say "yes" and what bearing that may have on the issue is something I simply do not know.

I have tried to get hold of folks in shots to let them know and ask if ok after the fact but mostly ask first if ok.(finding folks after the shot for permission is a rabbit trail and the rabbit wins) but once in a while when I can contact them,they are happy enough with a nice print of the image and let it go at that. Still, what legal ground I find at my feet is unclear.  I would not expect to be sued but may be asked to delete the image.  ???   Honestly, with permission from the subject, I have not lost a minutes sleep.

And, with an international forum, sorting could be difficult, indeed.
