Can I make a photo into a Watermark for the background

Is it possible to make a personal photo into a watermark or just use as a photo to put at the background of the template, I mean the page that surrounds the template page, the one in the furtherest background, I know I can change the colour but can I add a photo to that background?
IF so how please?

I am using Web Designer 6.

Thank You
Cheers Lyn

Yes. ;))

OK. :) So you want to know how, Right?

Hold down the Ctrl key and drag and drop the image onto the pasteboard area (the area around the page).

You can Ctrl drag and drop the image from the desktop, Windows Explorer, or the Bitmap Gallery.
