I'm working on building new site templates for ThemeForest and will have to create multiple template documents for the various page designs. I was wondering if I could, some how, create a shared header and footer graphic that all templates can use. I'm a programmer and dislike code duplication. I don't want to have graphic duplication either, as it'd make things more difficult if I choose to update a template header that is shared with many other templates.
Any help would be appreciated. Thanks for taking the time.
