@Drew, and then @DavCrav
@Drew... coherently incoherent? hehehe
@DavCrav - you're right, you're not. You're also rather wrong. I can take your photo on the street and then publish it commercially, with or without your consent. What I CANNOT do is make you appear to endorse a product, policy or concept. I also cannot use the image to commit libel against yourself or harrass you.
If I publish a sunset shot of The London Eye, I'm not making out there's any affiliation between myself and them.
Now if I took a picture of you eating a burger and then used that image as part of an advertising campaign for McDonuts... well, that would indeed require your consent because I'm making out you endorse a product.
However, if you're just part of a crowd walking past McDonut's, it's unlikely that I'd need your consent as you're simply part of the street furniture. This is especially the case if you cannot be clearly identified (eg, have your back to the camera).
