Microsoft Audience Network Ads are based on an image or video. When using images, what is the minimum number needed to begin?

The selected answer option, 1 Image, is correct because the minimum number of images required to begin running Microsoft Audience Network Ads is one. While using multiple images can enhance the variety and effectiveness of ads, advertisers can start their campaigns with a single image for their display ads. This allows for flexibility and simplicity in setting up campaigns, especially for smaller businesses or advertisers who may not have a wide range of creative assets at hand. However, using more than one image is often recommended for testing different variations and improving campaign performance through A/B testing, but one image is sufficient to initiate the campaign.
