Adding photo as full page watermark?

[Bernard and Sue Oliver]

Hi all

Trying to create a photo as a full A4 page watermark behind a poem.  
Can anyone advise if this is possible given the following info?........

iMac LCD
Panther
Epson Stylus Colour 680

Have found some info in Appleworks Draw docs  'Master Page' but this 
does not appear to provide for adding a photo.

Is my only work around to print out photo in say, draft, then overprint 
with the poem?

Thanks people and happy Friday!

Sue
