# Viewers

The **Viewers** object is a collection of all currently open standalone [image viewers](/directory-opus/manual/additional_functionality/viewing_images.md). It can be obtained via the [**DOpus**](/directory-opus/manual/reference/scripting_reference/scripting_objects/dopus.md)**.viewers** property.
