The Assets Library is a central repository for storing images to use in your surveys.
You can achieve a consistent look across multiple surveys, produced by multiple survey authors, by providing this central location where survey authors can access and share a library of images. For example, you can upload an approved set of product images that can be used in any survey that includes product related questions.
When necessary, you can assign access permissions to an image to restrict it to an individual team or teams, to the user that uploaded the image, or to Admins. By default, images are available to everyone with access to survey authoring.
