When you license an image at NetterImages.com or through our Licensing Dept, you will receive an Invoice. Unless otherwise specified in the type of license noted in your Invoice, (e.g., "Web use – 1 year"), a license is granted for one time use only. When you buy a license to print or duplicate up to a certain number of copies of an illustration within your product or project, that number includes reprints. If you wish to print more than the number you purchased a license to print, you would be required to purchase another license.
