Graphic used/referenced in one source and want to use it in another source

I have graphics from a project that I want to reuse in another project. If I copy these graphics into my graphic folder in the new project and import them into the new project, these graphics are stilled linked to the old project. How do I re-reference or link these graphics to the new project without having to import each one by openin the new project graphic folder, locating the graphic and import so each one is now linked/referenced to the new project? thanks
