If I obtain a license to use a Netter illustration, how long is the license good for?

When you license an image at NetterImages.comopens in new tab/window 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.
