Let's you want to use a picture of a Ferrari for example to promote Motor Trend magazine or some magazine about cars. Will they ban you? suspend you? not care?
What's the right approach to using juicy copyrighted images?
i'd say it's probably fine and Ferrari won't care as you'd be getting exposure for them with your magazine etc (Free to them).
Depends where the picture of the Ferrari came from. This is the kind of thing that stock photography sites are good for - either that, or a good look through some of the Creative Commons image sites.
Ferrari could, technically, sue you under Design Right, but they almost certainly won't unless you're doing something really dodgy. However, whether the photographer who took the shot will get upset if you're using it without his/her consent is another matter.
