# AttachImageWatermark
<a name="API_AttachImageWatermark"></a>

Attaches a watermark to a non-public AMI. The watermark is a structured identifier that automatically propagates to all derivative images created through [CreateImage](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateImage.html), [CopyImage](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CopyImage.html), and [CreateRestoreImageTask](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateRestoreImageTask.html).

Only the AMI owner can attach watermarks. Watermarks cannot be added to public AMIs.
