Many thanks for your help, Reinhard.

It works fine with some images, but if the image is too small (as 
http://www.ousia.tk/stamp.pdf) the resulting files are wrong 
(http://www.ousia.tk/add-background.pdf).

How can I place the stamp.pdf on a different position? Actually I need 
to be able to move the stamp position in different pages.

Thanks for your help,
