If I opt for exclusivity does it mean all my images are exclusive with moodboard?
No it doesn’t. Opting for exclusivity means you are interested in having us represent the images you indicate on the upload area exclusively. You can have some images represented exclusively and others non-exclusively. The exclusivity is on the images only and not on you as a supplier of images. If the editor agrees to representing this image or series of images exclusively then you cannot place them with other libraries. But any non-exclusive content can be placed elsewhere too.
