How to put one cartoon in the background of one book

Question

I would like to add one cartoon in the right margin of odd pages in one book. More precisely, ...

• ... the page #1 must contain the picture #1,
• ... the page #3 must contain the picture #2,
• ... the page #5 must contain the picture #3,
• ... and so on.

How can I achieve this ?

Answer 1

You can include the pictures using \includegraphics.

In order to ensure to get one cartoon per page, I would call it from the header rendering, using \srcpage2 for example.

Here is an example:

\documentclass[paper=a4]{scrbook}

\usepackage{scrpage2}
\usepackage{graphicx}
\newcommand{\cartoon}[1]{%
\begin{picture}(0,0)
        \put(#1,-200){\includegraphics[width=35mm]{xkcd/\thepage.jpg}}
\end{picture}
}
\cehead[\cartoon{-320}]{}
\cohead[\cartoon{220}]{}
\pagestyle{scrplain}
\usepackage{blindtext}

\begin{document}
\Blinddocument   
\end{document}

And the result, alternating margins:

Edit: Upon re-reading your question, I just saw you only wanted odd margins. Just remove the \cehead and you'll only have odd margins.
