Adobe PageMaker - Maintaining Links Between PageMaker and Photoshop (PageMaker 6.5/7)
If you maintain the link between a PageMaker document and an image you've created in Photoshop, you can have instant editing access to the original image. Use the Edit Original command in the edit menu or press [option] ([Alt] in Windows). Then, double-click on the image, which then opens in Photoshop. It's much easier than tracking down the filename of the image you want to make changes to in Photoshop.
