In the zenworks documentation i read the following.

Selecting this option installs the Imaging services and adds the Imaging role to the device. With this role, the device can be used as an Imaging server to perform all the Imaging operations, such as taking an image, applying an image, and multicasting an image. However, the ZENworks images are not replicated from the Primary Server to Imaging Satellites.

When in ZCC and i choose to configure satellite server i can check mark the imaging satellite role.
In the configure imaging satellite role i can choose Configure Imaging Content Replication

Can somebody tell me why you have this option if the documentation says it can not be done?
