Help Me Do My Job

The Situation: Need to make company letterhead in Word, where the images are locked into the background and can't be moved. I tried the advanced alignment screen --> absolute position, lock anchor. It works in regards to being able to type over the text succesfully, but you can still move the images if you click and drag. Anybody out there in internet land know how to accomplish this seemingly impossible feat? I've taken all of the online Word tutorials one girl can stand in a single day.
