[Tex/LaTex] Image behind text with fancy

fancyhdrgraphics

I want to have an image behind the page number in my latex document, and tried to write it like

\fancyhead[CE,CO]{\textcolor{white}{\thepage}}
\chead{\includegraphics[width=1cm]{img.eps}}

The problem is: When I first have the line with the page number, and then the image, I only get the image, and if I have the other way round, then I only get the number. How can I have the number in front of the image? Should I use a background image for that?

Here's one way:

\documentclass{article}
\usepackage{fancyhdr,stackengine,xcolor,graphicx}
\fancypagestyle{mystyle}{
\chead{\stackinset{c}{}{c}{}{\textcolor{red}{\thepage}}{%
  \includegraphics[width=1cm]{example-image}}}
}
\pagestyle{mystyle}
\begin{document}
My text
\end{document}

[Tex/LaTex] Column background image

You can insert an image in the background using the standard \includegraphics command, supplemented by a \raisebox{-\height}[0pt][0pt] to remove any vertical height/displacement.

The following minimal working example does exactly that, with the addition of any of the regular beamer overlay specification functionality:

\documentclass{beamer}
%\usepackage{graphicx}% http://ctan.org/pkg/graphicx
\begin{document}

\begin{frame}
  \frametitle{Background Test}

  \begin{columns}
    \column{0.3\textwidth}
      \only<2>{\raisebox{-\height}[0pt][0pt]{\includegraphics[width=\linewidth,height=4cm]{tiger}}}%
      \begin{itemize}
        \item Left Column 1
        \item Left Column 2
      \end{itemize}

    \column{0.7\textwidth}
      \begin{itemize}
        \item Right Column 1
        \item Right Column 2
      \end{itemize}
  \end{columns}
\end{frame}
\end{document}

enter image description here

I've set the width of the image to be exactly \linewidth, which is the width of the column that it is put in (the first). The height of the image is set to 4cm, but you can modify this as needed.

Of course there are other methods (using other packages), but this seems to be the most straight forward, since it uses the only the essential graphicx package, actually already included by beamer.

[Tex/LaTex] beamer: How to place images behind text (z-order)

You can define a custom environment backgroundblock like this:

\documentclass{beamer}

% For demonstration purposes only, can be removed without harm
\usetheme{Ilmenau}
\usepackage{lipsum}

% beamer: How to place images behind text (z-order)
% (http://tex.stackexchange.com/a/134311)
\makeatletter
\newbox\@backgroundblock
\newenvironment{backgroundblock}[2]{%
  \global\setbox\@backgroundblock=\vbox\bgroup%
    \unvbox\@backgroundblock%
    \vbox to0pt\bgroup\vskip#2\hbox to0pt\bgroup\hskip#1\relax%
}{\egroup\egroup\egroup}
\addtobeamertemplate{background}{\box\@backgroundblock}{}
\makeatother

\begin{document}
\begin{frame}
\begin{backgroundblock}{10mm}{10mm}
\includegraphics[width=50mm]{example-image-a}
\end{backgroundblock}
\lipsum
\begin{backgroundblock}{60mm}{47.5mm}
\includegraphics[width=50mm]{example-image-b}
\end{backgroundblock}
\end{frame}
\end{document}

It is used very much like the textpos environment textblock(*) in absolute mode, i. e.

\begin{backgroundblock}{<hpos>}{<vpos>}
<Content>
\end{backgroundblock}

places <Content> in a box at the coordinates (<hpos>,<vpos>) relative to the top left corner of the slide.

example slide with two backgroundblock environments

Explanation of the code

A box \@backgroundblock is added to the beamer template background which is later filled by the content of the backgroundblock environments. This shouldn't interfere with custom themes, as it is ensured that the box doesn't any occupy any space.
