Tailspin Toys are creating their first Microsoft Audience Network campaign. What is the minimum number of images they will need in order to do this?

For a Microsoft Audience Network campaign, Tailspin Toys needs a minimum of one image. While providing more images (up to 16) is recommended to allow the system to optimize and serve the best-performing ad creatives, only one image is strictly required to launch the campaign. Two, three, or five images are not the minimum requirement, although they represent better practices for ad variety and performance.
