Yes, it is not allowed for commercial usage without permission, whether a person is in it or not. When you put a picture out on the web as I did with this, it is for the most part fair game except when it is used in commercial advertising. Like I said this was my job for over 30 years. No biggie really in this case, except whoever builds their adds most defiantly should know better. Sort of neat to see they liked it though.
A copyright is created once a picture is used, or digitally stored or archived in any way. You do not need to actually file for a copyright.
Where it gets mirky is when you are for hire, contract or as an employee. In my case as a photographer for a major corporation, they owned all rights to my work.
A photographer working on an assignment for someone else, or say a wedding photographer or similar, would have to be spelled out in your contract as to who actually owns the rights.
Pictures the average person puts on the web are fair game for reuse for non commercial purposes, even if people are in the photos. That does not keep from somebody sueing you if you defame them in any way.
It also gets a little mirky if you are in the public taking photos as to their rights.
