# background image in LaTeX Beamer presentation

This post shows how one can change the background image in a Beamer presentation:

 <pre class="example">%% all slides


\usebackgroundtemplate{ \includegraphics[width=\paperwidth, height=\paperheight]{my_bg_image} }

%% single slide { \usebackgroundtemplate{\includegraphics[width=\paperwidth]{my_bg_image}} \begin{frame} \frametitle{Frame with nice background} \begin{itemize} \item 1 \item 2 \item 3 \end{itemize} \end{frame} }

The above method spans the image to cover the entire page size. To include a smaller image and center it, do this:

 <pre class="example">\usebackgroundtemplate{%


\vbox to \paperheight{\vfil\hbox to \paperwidth{\hfil\includegraphics[width=1.5in]{name.jpeg}\hfil}\vfil} }

(I asked this question on the Tex.SX since \hspace{4.5cm} works but \vspace{4.5cm} did not.)
