Not so, evidentally. How many of you use Flickr? Have you seen this video on CNN where a girl had her picture taken at a church BBQ, and the person who took the photo posted it in his flickr account. Next thing you know, her photo is all over Australia in a major Virgin Australia ad with such tag lines as 'Free text Virgin to Virgin'. She had no knowledge of this use of her likeness. Flickr says, and is also noted in the small print of the Virgin ad, that images used were used under fair use policies.
I know that if we say or post anything on the net, we should expect it to be used, copied, quoted, anything since we no longer have control over it. In computer security it is always said that the only way to totally secure a computer is to never turn it on in the first place. That said, it just amazes me that a major corporation would use a photo someone found on the web without securing permission, especially since it is a MINOR in the image!
