# ImageMapping
<a name="API_ImageMapping"></a>

Specifies image mappings that workflow tasks can use. For example, you can replace all the task references of a public image to use an equivalent image in your private ECR repository. You can use image mappings with upstream registries that don't support pull through cache. You need to manually synchronize the upstream registry with your private repository.
