always a can of worms this

my rule of thumb would be - is the item in the photo recognisable as a specific [intellectual property protected] item

if so is your usage likely to infringe on their legitimate expectation to make money from it marketing wise etc - in the case of coke like you say thats a given

but it is a rule of thumb - for the chapter and verse you need a legal guy
