Creating an Add-On Image
An add-on image is an archived collection of files that will be applied to an existing Windows*
installation on a target computer. The existing partitions and files on the target computer 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 Common tab) of the
Application object. For details, click Help on that property page.
An add-on image created in this manner is not fully installed on the target computer until after
the computer reboots from being imaged and Application Launcher/Explorer starts up and
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. For more information, see “Image Explorer (IMGEXP.EXE)” on page 219.
Generally, an add-on image created in this manner doesn’t require any post-processing on the
target computer. 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 will be applied to the
registry automatically when the computer reboots after being imaged, if the imaging agent is
installed on the computer. For more information, see “Customizing an Image” on page 210.
Customizing an Image
After you have created a base or add-on image as explained in the previous sections, you can
customize it using the Image Explorer utility. Specifically, you can:
Compress the image
You can compress an image (including images created by previous versions of ZfD) by 40-
60% of the original file size. There are three compression options. Optimize for Speed takes
the least amount of time but creates the largest compressed image file. This option is used by
default when an image is created. Optimize for Space creates the smallest image file but may
take a significant amount of time. Balanced is a compromise between compression time and
image file size.
(You can also use the options on the ZENworks Imaging Configuration property page for the
workstation object in ConsoleOne to specify compression options if you do not want the
default, Optimize for Speed.)
Purge deleted files
Excluded or hidden files and folders can be completely removed from an open image. This
saves space in the image if you no longer want to include the files.
Exclude individual files and folders from the image
