For install image transmissions:
--------------------------------
WDSUTIL [Options]
        /Get-MulticastTransmission
        /Image:
        [/Server:]
        [/Details:Clients]
        /ImageType:Install
        [/ImageGroup:]
        [/Filename:]

[/ImageGroup:]
        The image group containing the image that is associated with
        the transmission.  If not specified and only one image group
        exists on the server, then that image group will be used.  If
        more than one image group exists on the server, then the image
        group must be specified.

[/Filename:]
        If the source image cannot be uniquely identified by name, you
        must specify the file name.
