It has been a while. Lets see if I can remember the steps.

You will need stuff it and disk copy on your centris.

Copy the images onto your Centris and unstuff them.

Open disk copy.

Select open from the file menu.

Select your disk image.

Then on one of the menus is an open to write the image.

Those aren't the exact step but it is as close as I can recall and it should get you close enough to figure it out.
