Copyright for book cover images
We are putting together an app called "FigureOutFrench Expressions" which uses quotes from French novels. I have gained copyright permission from the publishers for all of the quotations I will be using but what about the image of the book cover? Do I need copyright permission for that? Of course publishers might well be happy for us to use the cover and so say yes because it's free advertising for them, but do they have the right to let us use it?
