If you can boot the target computer using WinPE, and connect to a network share where an image is stored, then you can certainly pull down an image onto the machine. However, it is unclear from your posting whether you want to "push" or to "pull" and image onto the target machine.
Ghost 8.2 is a truly ancient release and for enterprise environments, you should be looking at Ghost Solution Suite 2.5.1.2266 or later. This offers push capabilities.
Do bear in mind however, that if the operating system you are deploying is Windows 7, do you have the network bandwidth internationally to transfer many Gb of image to the target machine? Or do you intent to have image shares held locally in each territory?
If you are imaging new computers, why not use a portable, bootable USB hard disk to image each machine. This is going to be a lot faster than imaging over a network.
