In this post, we are going to see how to use an image as a frame background in beamer, both as the default background and as the background for a given frame.

## 1. Change default background in all slides

Here is a minimal working example on how to do so:

% Background image in Beamer
\documentclass{beamer}

% Theme choice
\usetheme{Berlin}

\setbeamertemplate{background}
{
\includegraphics[width=\paperwidth,height=\paperheight]{MyBackground.jpg}
}

\title{How do you add a background image in LaTeX Beamer?}
\author{\LaTeX{}-beamer.com}

\begin{document}

% Title page
\maketitle

% Simple frame
\begin{frame}{A standard frame}

\end{frame}

\end{document}

Compiling this code yields:

We used \setbeamertemplate{background}{} command and the image with size equal to the slide size (paper width x paper hight). The image is included using includegraphics command.

## 2. Change background of a specific slide

To change the background of one slide (or more) in Beamer, we put the command \setbeamertemplate{background} and frames between braces.

Here is an illustrative example that changes the background of one frame:

% Change background of one slide
\documentclass{beamer}

% Theme choice
\usetheme{Berlin}

\title{How do you add a background image in LaTeX Beamer?}
\author{\LaTeX{}-beamer.com}

\begin{document}
\maketitle

{
\setbeamertemplate{background}
{
\includegraphics[width=\paperwidth,height=\paperheight]{MyBackground.jpg}
}
\begin{frame}{A standard frame}

\end{frame}
}

\end{document}

Compiling this code yields:
