Hi Guys, your are pointing a very hot internet problem, I mean Copyright !
In my mind, there are two levels :
First, the "gentlemen" level : it's not correct to put on his site pictures that you've copied on other sites....except perhaps if those pics are published on their original site for commercial purpose !
I publish on my site only the pictures that has been directly send to me by their owners or pictures taken by myself.
All other cases are submitted to a "gentlemen agreement". Best way to publish is to ask autorisation !!
Second, the law level :
If you have taken a picture, you're of course the owner of the picture (copyright) and you can of course forbid any publication of it......but you need to be able to proove that you're the owner of the pic and this is very difficult, especially with digital pics (without negatives !).
To resume, if you don't want your pics to be diffused every where without control, don't put them on any site......
Concerning the licensplate problem, we have already talked about this and I understand very well the position of some of you who prefer not to have their licensplatenumber published.......but, once again, If you ask a correct people to delete it, it will be done but, if somebody takes a pic of your car (and own copyright on the pic), you have no legal way to forbid him to publish the pic on his site since licenseplatenumber is something public.......
