I think if it is created as a template (.dot) and saved as such you should see it in the preview.
In Word 2003, when you click File | New and On My Computer and bring up the Template window you are able to preview, on the right hand side, the templates that MS has provided for you.
Is there a way to create a preview for user created templates?
Thanks.
