Set an image as a full-page background

Helo

Is it possible to set an image as a full page background, with no margins 
around? It should be placed from the top margin to the bottom (even under 
header and footer) and from the left margin to the righ, not only under 
the content, but stretched on the entire page. For example, for A5 page, 
the image should have 210x148mm.
