Thanks. I just realized that my question wasn't put well. What I want  
is to tell Pdf(la)tex to scale down the document. Of course, I could  
downsample the individual images, but I'm looking for a solution  
which would allow to keep one version of the original images and have  
different pdfs created depending on the resolution I need on a  
specific occasion. Let's say a low resolution to put the document on  
the web and a high resolution for printing. So I don't want to  
manipulate the images but have pdftex downsample them.
