# EnableAllowedImagesSettings
<a name="API_EnableAllowedImagesSettings"></a>

Enables Allowed AMIs for your account in the specified AWS Region. Two values are accepted:
+  `enabled`: The image criteria in your Allowed AMIs settings are applied. As a result, only AMIs matching these criteria are discoverable and can be used by your account to launch instances.
+  `audit-mode`: The image criteria in your Allowed AMIs settings are not applied. No restrictions are placed on AMI discoverability or usage. Users in your account can launch instances using any public AMI or AMI shared with your account.

  The purpose of `audit-mode` is to indicate which AMIs will be affected when Allowed AMIs is `enabled`. In `audit-mode`, each AMI displays either `"ImageAllowed": true` or `"ImageAllowed": false` to indicate whether the AMI will be discoverable and available to users in the account when Allowed AMIs is enabled.

**Note**  
The Allowed AMIs feature does not restrict the AMIs owned by your account. Regardless of the criteria you set, the AMIs created by your account will always be discoverable and usable by users in your account.
