 - `name` - (Optional) The name of the image. If not provided it will be randomly generated.
 - `architecture` - (Optional, default `x86_64`) The architecture the image is compatible with. Possible values are: `x86_64` or `arm`.
 - `additional_volume_ids` - (Optional) List of IDs of the snapshots of the additional volumes to be attached to the image.
-
--> **Important:** For now it is only possible to have 1 additional_volume.

 - `tags` - (Optional) A list of tags to apply to the image.
 - `public` - (Optional) Set to `true` if the image is public.
 - `zone` - (Defaults to provider `zone`) The [zone](../guides/regions_and_zones.md#zones) in which the image should be created.
