Image as background

Setting an image of the artists work as the background for the entire website:

Select 'Design', 'Wallpaper and Icon' ensuring 'Show background' is not selected. Press 'Choose Image' then choose any image from the file.

The image taking up the entire page is effective on the homepage because it is a simple way of introducing the viewer to my work.

However, it can't be done without effecting every page on the website; the background and the images of my work clash, and the background is distracting.
