# Is it possible to replace a beamer side bar by an image?

Everything is in the question. I would like to build a template for presentation (similar to a corporate PP presentation) including a background image on the left side of the slide. I was thinking of using the Hannover theme and replacing the color left side bar by the image, without success yet. Any suggestion welcomed.

EDIT : The solution proposed by @samcarter works fine for the current slides, but I could not succeed to make it work for title slide :

\documentclass[table]{beamer}
% % % % % % % % % % % % % % % % % % % % % % % % % % % % % Beamer settings
\usetheme{Hannover}

\makeatletter
\setbeamertemplate{sidebar}{\includegraphics[width=1.5\beamer@sidebarwidth,height=\paperheight]{images/title_sidebar}} %
\setbeamertemplate{sidebar left}{\includegraphics[width=1.5\beamer@sidebarwidth,height=\paperheight]{images/slide_sidebar}}
\makeatother

% % % % % % % % % % % % % % % % % % % % % % % % % % % % %  Other packages
\usepackage[utf8x]{inputenc}
\usepackage[T1]{fontenc}

\title[short title\hspace{0.25\textwidth}\hfil\insertpagenumber]{Looooooooooooooooong title of the presentation}
\date[xxx 2018]{Congress name\\
Congress date and place}
\author[X]{authors}%
\institute{\centering
\includegraphics[scale=0.4]{Institution_logo}
}

\begin{document}
\frame[plain]{\titlepage}

\begin{frame}
\frametitle{Current slide}
Bla bla
\end{frame}
\end{document}


Why simply substituting 'sidebar left' by 'sidebar' doesn't work ?

• Don't specify both width and height, just one of them. – user36296 Apr 19 '18 at 13:27
• Please see my edited answer for the title page – user36296 Apr 19 '18 at 13:27

\documentclass{beamer}
\usetheme{Hannover}

\makeatletter
\setbeamertemplate{sidebar left}{\includegraphics[width=\beamer@sidebarwidth,height=\paperheight]{example-image}}
\makeatother

\begin{document}

\begin{frame}
abc
\end{frame}

\end{document}


(for the real world case, provide an image with suitable dimensions and specify either the width or the height, but not both)

To use this also for the title page:

{
\setbeamertemplate{footline}{}
\begin{frame}
\titlepage
\end{frame}
}

• Thanks a lot ! Exactly what I wanted, I only need to slightly adjust the width of the side bar to fit and not distort the image. – DRi Apr 17 '18 at 12:41
• Sorry to come back to this issue, this works OK for the running slides and I thought I could do the same for the titile slide by substituting 'sidebar left' by 'sidebar', but it doesn' t work. Any hint ? – DRi Apr 19 '18 at 8:43
• @DRi Can you make a MWE? – user36296 Apr 19 '18 at 9:06
• OK but it just puts the same sidebar as on the other slides, on the title page. And, yes, I am picky, but I'd rather have a special image for the title page sidebar – DRi Apr 19 '18 at 14:02
