Wordpress watermark

[Faan]

Has anybody got any idea how to put a "watermark" on a WP page.

I did a basic website with WP for a symposium I am organising. What I would like to do is to put something in the background of every page as a sort of a "watermark" It is probably a plugin I have to install, but I am not sure where to look.

I would appreciate some help.

Thanks

Does it have the ability to make something transparent? I put watermarks on by adding text and then making the text about 60-70% transparent. I don't use Wordpress though.
