Background Image/Text. If you're looking to add a watermark image to pages in your dissertation using LaTeX, have a look at the code in the link above. The macros \paperheight and \paperwidth may not work correctly for you, so use the actual dimensions of your paper (for example, in the Letter paper format I used 11in for the paperheight and 8.5in for the paperwidth). This tip uses the eso-pic package and there are a whole slew of commands in this package (warning, PDF file). The macro \AddToShipoutPicture{}{} will add the picture to the pages from the time you call it until you clear the image using the command \ClearShipoutPicture. It's a great way to add a watermark such as your school seal on the dissertation approval page or even your title page.
