You'll need at least 9.0 SP3 (or 9.5). You will either have to make the system you're imaging from a preffered target or figure out what drivers you need placed in the image manually. Your choices for how to get it out there are LANDesk's copy content, Microsoft Synctoy, or FreeFileSync.
If you use 9.0 SP3 you'll need to read this http://community.landesk.com/support/message/72616#72616
We have preferred servers set up at four remote sites (these sites have at least one onsite IT employee).
I set up a desltop at each and installed the PXE Rep on them, then I configured them as preferred servers with two sources: drivers and images. These sources are replicated whenever I initiate it (eg when a change is made to them). This way all the content is copied locally instead of going out across the WAN. For OSD images it takes less than 10 minutes. For end-to-end provisioning templates it takes about 1 1/2 hours. If I spend some time tweaking the process and adding a source for packages (and replicating it) I can probably cut this down to about 40 minutes.
For branches that don't have onsite IT we image the machine before shipping it.
