How to maintain one menu for several pages

Hi,
I'm not sure if this post belongs in Photoshop or Dreamweaver as it involves both of those products.. but I'll try here first.

I have created a Photoshop template that I want to use for a dozen or more pages on a given webpage I am making. The navigation buttons run down the center of the Photoshop graphic, and I have cut and exported them to a HTML & Image file directory. Now if I use this Photoshop template to to generate a dozen different pages, everytime I copy/rename it to another page, Dreamweaver renames every graphic in the page. So I have to link each graphic navigation button separately, a very time consuming process. Now imagine that I want to change JUST the navigation buttons by adding/deleting/renaming a navigation button, I have to do this separately for every single page as well as having to relink every single button in every single page.. hours of work for a small change.

I want to find a way to keep the menu navigation buttons in a single file that each instance of the page references so that if I do this, I only have to edit ONE file, and it gets included and NOT renamed for all existing and new instances of the pages.

As Dreamweaver renames every graphic I don't know how to do this.

As the navigation graphics are buried in the center of the graphics of the page I haven't found a facility in Photoshop or Dreamweaver to do this (I could do them separately yes, but is there a way to say "include" this external file for navigation at the appropriate place?), and I haven't been able to figure out a work flow either. Any help with this is greatly appreciated.

I suspect this sounds pretty confusing, I hope it makes sense, thanks much for help from anyone.




Thanks!

Brian
