Petit test
Guess first, no penalty. An AI image for your ad looks great as a thumbnail. Where do problems usually hide?
People are often less happy with AI help on visual work. In a Microsoft Research study of 200,000 Bing Copilot conversations, the work activities with the lowest share of positive feedback "include five visual design and five data analysis" activities (Working with AI).
AI images fail in three places: logos, text and hands. A sign can carry invented lettering, a laptop can carry a mark that looks like another company's logo, and fingers can come out wrong.
Copyright and trademark rules apply to images just as truth rules apply to copy. Platforms and some countries also have rules about labeling AI-made images, and those rules keep changing, so check each platform's own policy pages before a campaign.
