You could use a section break solution as Carol describes, or you can simply
insert the graphic with its layout set to 'behind text' on the required
page, when you have finished editing the document. A watermark is simply a
(usually pale) graphic inserted as a background image. It is normally
inserted in the header view as watermarks are usually required to repeat on
each page - but they don't have to be.
If you later need to select a background image, you can do so using the
white arrow selector on the drawing toolbar.
