Image in return address labels

[Nerm]

Does anyone know how to add an image into address labels in Word 2007 and have Word save the image in the return address label so that it is always in the default label? I can get the first part of this working pretty easy by just adding an image to a document and then adding the image from the document into the return address label. What I am having a hard time doing is getting Word to save the image and keep it in the default return address label. Everytime I close Word and reopen I have to import the image again into the document and into the return address label.
