Coverage checkerDoes LinkedIn show who made an AI image?
It shows who signed it. Images and video with Content Credentials get a C2PA icon on LinkedIn, and the panel behind it shows whether AI was used, the app, the creator, the issuer and the date. The issuer is whoever signed the manifest: your supplier, unless you sign under your own name.
