(This tutorial is also available as an OpenOffice.org Writer file that actually has the screenshots)
To insert a background 'watermark' in your OpenOffice.org Writer documents,
1.#2.#Choose the tab labeled 'Background'3.#In the first select box, choose As Graphic4.#Use the 'Choose' button to browse your hard drive for the graphic you want to use. Note that a few suitable graphics can be found at www.nbptgnus.org5.#Use the 'Type' options to determine the placement of the image, and whether it repeats (tiles) across the page.
This is just boring text but you can't miss the background watermark. Perhaps it is just a bit too large, and a teeny bit too dark. Adjust to your liking. Images and tutorial by Greg Rundlett, all rights reserved under the GNU Free Documentation License.
