# how to group images in a figure?

I want to group images and assign the same sub-figure number in a figure consisting of several such groups. Please have a look at the following image to understand my question properly.

• you can use subfigure ctan.org/pkg/subfig – rpapa Jun 11 '15 at 20:54
• @rpapa: I think that it will provide a number (i mean (a), (b), (c)...) to each sub-figure. But I need that a number is provided to a group of three figures only as depicted in my sample image above. – skm Jun 11 '15 at 20:58
• @skm use 3 \includegraphics{...} for each of the groups with subfig then? – user31729 Jun 11 '15 at 21:08
• @ChristianHupfer: May be, i did not understand your suggestion properly but i think that in that case, each group will become a separate figure which will not look good. – skm Jun 11 '15 at 21:25

Two options, but the general idea is the same: to use one subfigure environment (requires subcaption) or \subfloat command (requires subfig) for each group.

Here's one option using the powerful subcaption package:

\documentclass{article}
\usepackage{subcaption}
\usepackage{graphicx}

\begin{document}

\begin{figure}
\begin{subfigure}{\linewidth}
\includegraphics[width=.3\linewidth]{example-image-a}\hfill
\includegraphics[width=.3\linewidth]{example-image-a}\hfill
\includegraphics[width=.3\linewidth]{example-image-a}
\caption{}
\end{subfigure}\par\medskip
\begin{subfigure}{\linewidth}
\includegraphics[width=.3\linewidth]{example-image-b}\hfill
\includegraphics[width=.3\linewidth]{example-image-b}\hfill
\includegraphics[width=.3\linewidth]{example-image-b}
\caption{}
\end{subfigure}\par\medskip
\begin{subfigure}{\linewidth}
\includegraphics[width=.3\linewidth]{example-image-c}\hfill
\includegraphics[width=.3\linewidth]{example-image-c}\hfill
\includegraphics[width=.3\linewidth]{example-image-c}
\caption{}
\end{subfigure}
\caption{Some grouped images}
\end{figure}

\end{document}


The output:

And now with the help of the subfig package:

\documentclass{article}
\usepackage{subfig}
\usepackage{graphicx}

\begin{document}

\begin{figure}
\subfloat[]{%
\begin{minipage}{\linewidth}
\includegraphics[width=.3\linewidth]{example-image-a}\hfill
\includegraphics[width=.3\linewidth]{example-image-a}\hfill
\includegraphics[width=.3\linewidth]{example-image-a}%
\end{minipage}%
}\par
\subfloat[]{%
\begin{minipage}{\linewidth}
\includegraphics[width=.3\linewidth]{example-image-b}\hfill
\includegraphics[width=.3\linewidth]{example-image-b}\hfill
\includegraphics[width=.3\linewidth]{example-image-b}%
\end{minipage}%
}\par
\subfloat[]{%
\begin{minipage}{\linewidth}
\includegraphics[width=.3\linewidth]{example-image-c}\hfill
\includegraphics[width=.3\linewidth]{example-image-c}\hfill
\includegraphics[width=.3\linewidth]{example-image-c}%
\end{minipage}%
}
\caption{Some grouped images}
\end{figure}

\end{document}


The output:

Another option might be to use the floatrow package.

• Thanks a lot. It worked perfectly fine. thank you so much. – skm Jun 12 '15 at 19:19
• @skm You're welcome! Glad I could help. – Gonzalo Medina Jun 12 '15 at 21:28
• Note alo the discussion here about subcaption vs. subfig. – Davor Josipovic Jan 2 '17 at 16:04

try this

\begin{figure}{h}
\subfigure[caption 1]{\label{...}
\includegraphics{img1-a}\hspace{1em}
\includegraphics{img1-b}\hspace{1em}
\includegraphics{img1-c}
}
subfigure[caption 2]{\label{...}
\includegraphics{img2-a}\hspace{1em}
\includegraphics{img2-b}\hspace{1em}
\includegraphics{img2-c}
}

\caption{}
\label{}
\end{figure}

• This requires loading the subfigure package which is obsolete and shouldn't be used anymore. – Gonzalo Medina Jun 11 '15 at 22:30
• Besides, using just h as placement specifier is a recipe for disaster and the placement specifier goes as optional argument for figure and your code snippet uses it as mandatory argument. – Gonzalo Medina Jun 11 '15 at 22:41
