XP sp2 / Office 2003

Hi! I created a custom template. In the template there is a .tiff image that
I inserted using Insert->Picture->From File.
When I create a new document based on this template I see the graphics in
the header. It works OK on my and my coworkers PC's. Some users, however,
reported that new documents do not have graphics in the header.
I went further and created a new template on a pc experiencing the problem.
It did not help.

How do I go about troubleshooting this problem? Is there any setting I can
toggle ?

Many Thanks in Advance,
