Adding images Prerequisites Before you can add an image, you must include it as a resource in the resource set you intend to use. When you save an overlay that includes embedded or linked images, the images are automatically included in the resource set. Therefore, if you add an image by copying it from the clipboard (embed the image) or by dragging it from the Windows Explorer (link the image), you do not have to include it in the resource set. To add an image from a resource set 1 Select File > Import > Image. The Select Resource dialog box opens. 2 Browse to the correct folder and double-click the image. 3 Position the image using the mouse.
