# Images in a presentation

This is my first time being here. The site is such an asset. Asking this only because I couldn't get it done. Question. I want to insert two (may be three) images with captions for each. I was referring this: This is my code for that particular frame:

\usepackage{graphicx}
\usepackage{float}

\begin{frame}
\begin{tabular}{ccc}
\subfloat[caption]{\includegraphics[width = 2in]{image1.jpg}} &
\subfloat[caption]{\includegraphics[width = 2in]{image2.jpg}}
\end{tabular}
\end{frame}


I get an error saying: \subfloat outside float. I'm using the online .tex editor Overleaf.

Any help is much appreciated.

In a presentation often have little sense numbered subcaptions and the superfluous "Figure:" statement. As the issue with all of this is solved in another answer, my suggestion is not use at all figure floats, captions or any related package:

\documentclass{beamer}
\begin{document}
\begin{frame}\centering
\begin{columns}
\begin{column}{.3\linewidth}\centering
\includegraphics[width=\linewidth]{example-image-a}\par
The image A
\end{column}
\begin{column}{.3\linewidth}\centering
\includegraphics[width=\linewidth]{example-image-b}\par
The image B
\end{column}
\begin{column}{.3\linewidth}\centering
\includegraphics[width=\linewidth]{example-image-c}\par
The image C
\end{column}
\end{columns}
\bigskip
The main caption
\end{frame}
\end{document}

• Why not a tabular? – egreg Apr 2 '17 at 8:35
• @egreg This morning I was not quite "tabulator". That's all. :D – Fran Apr 2 '17 at 18:01

The solution is to use figure outside (it's a float and it's for images):

\begin{frame}
\begin{figure}[h] %<-- NEW
\begin{tabular}{ccc}
\subfloat[caption]{\includegraphics[width = 2in]{image1.jpg}} &
\subfloat[caption]{\includegraphics[width = 2in]{image2.jpg}}
\end{tabular}
\end{figure} %<-- NEW
\end{frame}


If you'd like to have many options with your captions probably you should switch to the package subcaption (uses caption) and this approach:

\begin{frame}
\begin{figure}
\begin{subfigure}{.45\textwidth}
\centering
\includegraphics[width = \linewidth]{example-image-a.jpg}
\caption{Caption}
\end{subfigure}\hfill
\begin{subfigure}{.45\textwidth}
\centering
\includegraphics[width = \linewidth]{example-image-b.jpg}
\caption{Caption}
\end{subfigure}
\caption{Test}
\end{figure}
\end{frame}

• @ TeXnician, it worked. Thank you very much. Could you please tell me how to adjust the dimensions of the images ? – Eureka Apr 1 '17 at 17:30
• @Eureka There is a parameter width you already issued and adjusted. – TeXnician Apr 1 '17 at 17:32
• the way it appears now is one image is taller than the other and two are closer to each other. That's what I want to change. – Eureka Apr 1 '17 at 17:33
• @Eureka Please edit your question and post a screenshot of what you want to adjust. – TeXnician Apr 1 '17 at 17:34
• if you use, for example \includegraphics[width = \linewidth]{example-image-b.jpg}, than \centering its position inside subfigure has no sense ... and can/should be omitted :) – Zarko Apr 1 '17 at 21:52
