Insert graphics/figures as watermark

[BDW]

Can anyone help me to add a figure (pdf/jpg/png) file as a watermark?
It also needs to be shaded (like 50% transparent) and preferably
automatic converted to grey-scale when it is a colour-file. One
package can only add a text as watermark (shaded), the other one can
add a figure, but without transparency/shading. I already used google
a zillion times without help.

I currently use the following code:

\newcommand\BackgroundLogo{
\put(0,0){
\parbox[b][\paperheight]{\paperwidth}{%
\flushright
\includegraphics[width=0.25\paperwidth, keepaspectratio]
{page_logo.jpg}%
\textcolor{white}{MMM}
\vfill }}}
which adds a figure in the topright corner (without shading). The
triple M is added to preserve some distance between the figure and the
border of the paper.

\documentclass{article}
\usepackage{graphicx,eso-pic,lipsum}
\AddToShipoutPicture{%
  \put(0,0){\includegraphics[height=297mm,width=210mm]{peter.jpg}}}
\begin{document}
\lipsum[1]
\lipsum[2]
\lipsum[3]
\end{document}

Just make sure that the image is proportioned correctly for the paper size, and that the image is monochromed and gray-scaled appropriately (LaTeX cannot do this: you must use a graphics package like GIMP to do that first).

Google for latex watermark image, look at the first hit, and go to the section "UPDATE: Neno wants to know how to use a picture instead of text." I just cut it down from there.

Thanks, Peter. I just managed to convert the eps files to grayscale-
pdf with GSView. I couldn't configure GIMP to use ghostscript, because
of administrator-rights issues.

monochrome and grayscale are basically the same right? Is there a way
to adjust opacity/transparency with GSView? Maybe as an option to
pdfwrite?

Are the eps files bitmaps or vectors?
GIMP would just convert the eps files to a bitmap anyway.

Not quite, but for all practical purposes, yes.

No. PostScript has no transparency. If you want transparency, you must use PDF.
But if these are for a watermark, why do you want transparency? They will go underneath everything else, so just make them very pale grey.
 

Maybe as an option to pdfwrite?

I haven't looked.
