An add-on image is an archived collection of files to be applied to an existing Windows installation on a target workstation. This is sometimes referred to as an application overlay. The existing partitions and files on the target workstation are left intact, except for any files that the add-on image might update.
An add-on image typically corresponds to an application or utility, or simply to a set of data files or configuration settings. There are two ways to create an add-on image, each resulting in a different kind of add-on image:
Produce the add-on image from an Application object
You do this in ConsoleOne by using the Imaging property page (on the tab) of the Application object. For details, click on that property page.
An add-on image created in this manner is not fully installed on the target workstation until after the workstation reboots from being imaged, the user logs in locally, and Application Launcher/Explorer starts up and force runs the new Application object. Deploying the image is essentially another way to distribute an Application object.
Drag files into a new image archive using Image Explorer
You do this by starting Image Explorer, dragging files and folders from an existing Windows installation into the new image archive, and saving the archive to a file with a .zmg extension (case-sensitive). For more information, see Section 63.1, Image Explorer (imgexp.exe).
Generally, an add-on image created in this manner doesn’t require any post-processing on the target workstation. It is simply a set of files that are copied to the appropriate locations on the hard disk, much like what happens when you unzip a WinZip archive. One exception is that the add-on image can contain Windows registry (.reg) files that are applied to the registry automatically when the workstation reboots after being imaged, if the ZENworks Imaging Windows Agent is installed on the workstation. For more information, see Section 59.3, Using Image Explorer to Customize an Image.
