I have several images and I must put their names below them. Moreover, I need to give the name of the group of that images too (for example, "first layer", "second layer" ect as show below). I need to have something as shown in the figure below.

image

IMPORTANT: In my case, a group of images may contain more than one row. I mean, the "(a) first layer" may contain more than 3 images and hence can be a group of images in more than one row.

Two options:

  1. Using some tabulars for each layer and the subcaption package:

    enter image description here

    The code:

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

\begin{document}

\begin{figure}
\begin{minipage}{\linewidth}
  \centering
  \begin{tabular}{ccc}
  \includegraphics[width=.28\linewidth,height=1cm]{example-image-a}
    & \includegraphics[width=.28\linewidth,height=1cm]{example-image-b}
    & \includegraphics[width=.28\linewidth,height=1cm]{example-image-c} \\
  First image & Second image & Third image \\  
  \includegraphics[width=.28\linewidth,height=1cm]{example-image-a}
    & \includegraphics[width=.28\linewidth,height=1cm]{example-image-b} \\
  Fourth image & Fifth image &
  \end{tabular}
  \subcaption{First layer}
  \end{minipage}\par\bigskip
  \begin{minipage}{\linewidth}
  \centering
  \begin{tabular}{ccc}
  \includegraphics[width=.28\linewidth,height=1cm]{example-image-a}
    & \includegraphics[width=.28\linewidth,height=1cm]{example-image-b}
    & \includegraphics[width=.28\linewidth,height=1cm]{example-image-c} \\
  First image & Second image & Third image \\  
  \end{tabular}
  \subcaption{Second layer}
  \end{minipage}
\caption{a figure with some layers of subfigures each with its own name and each layer with a subcaption}
\end{figure}

\end{document}

    Above I used a standard tabular with three c type columns; if the text below the images should span more than one line, you could use tabularx from the tabularx package and centered X columns, as the option below illustrates.

  2. Since the OP is using subfig, the subcaption package cannot be used; here's an approach using the same idea as before, but with tabularx and the subfig package:

    \documentclass{article}
\usepackage[caption=false]{subfig}
\usepackage{graphicx}
\usepackage{tabularx}

\newcolumntype{Y}{>{\centering\arraybackslash}X}

\begin{document}

\begin{figure}
\subfloat[First layer]{%
\begin{minipage}{\linewidth}
  \centering
  \begin{tabularx}{\linewidth}{YYY}
  \includegraphics[width=\linewidth,height=1cm]{example-image-a}
    & \includegraphics[width=\linewidth,height=1cm]{example-image-b}
    & \includegraphics[width=\linewidth,height=1cm]{example-image-c} \\
  First image & Second image & Third image \\  
  \includegraphics[width=\linewidth,height=1cm]{example-image-a}
    & \includegraphics[width=\linewidth,height=1cm]{example-image-b} \\
  Fourth image & Fifth image &
  \end{tabularx}
  \end{minipage}}\par\medskip
\subfloat[Second layer]{%
  \begin{minipage}{\linewidth}
  \centering
  \begin{tabularx}{\linewidth}{YYY}
  \includegraphics[width=\linewidth,height=1cm]{example-image-a}
    & \includegraphics[width=\linewidth,height=1cm]{example-image-b}
    & \includegraphics[width=\linewidth,height=1cm]{example-image-c} \\
  First image & Second image & Third image \\  
  \end{tabularx}
  \end{minipage}}
\caption{a figure with some layers of subfigures each with its own name and each layer with a subcaption}
\end{figure}

\end{document}

  • It throws an error Undefined control sequence. \subcaption because I am already using \usepackage[caption = false]{subfig} – skm Jul 27 '15 at 22:10

    @skm You should have mentioned that in the first place! subcaption and subfig are incompatible. In some minutes I'll update my answer using subfig instead. – Gonzalo Medina Jul 27 '15 at 22:12
  • Actually, I am already using \usepackage[caption = false]{subfig} and hence I cannot use \usepackage{subcaption} in combination to it – skm Jul 27 '15 at 22:12
  • @skm Please see the updated answer under the "Update" section. – Gonzalo Medina Jul 27 '15 at 22:16
  • The method works but the name of the group for example "(a) first layer", "(b) Second Layer" are in smaller font than the name of individual images. This seems a little strange. Is there any solution for this problem? – skm Jul 27 '15 at 22:26

    @skm If you want normal size for the subcaptions load the subfig package like this: \usepackage[caption=false,font=normalsize]{subfig}. The other option is to use something like \small First image & \small Second image... inside the table to reduce the font size for the image names. – Gonzalo Medina Jul 27 '15 at 22:36
  • thanks a lot. It is something which I have been looking for a long time. Thanks a lot. – skm Jul 27 '15 at 22:41
  • @skm You're welcome. Glad I could help. – Gonzalo Medina Jul 27 '15 at 22:52
  • Your suggestion worked but actually I have several images in a figure and hence now these images are getting hide behind the bottom of the page. I am facing a similar situation which I faced here http://tex.stackexchange.com/questions/245689/page-break-between-images-of-a-figure – skm Jul 30 '15 at 20:51

You can have multiple rows, e.g. look at this example from ClassicThesis:

begin{figure}[bth]
    \myfloatalign
    \subfloat[Asia personas duo.]
    {\includegraphics[width=.45\linewidth]{gfx/example_1}} \quad
    \subfloat[Pan ma signo.]
    {\label{fig:example-b}%
     \includegraphics[width=.45\linewidth]{gfx/example_2}} \\
    \subfloat[Methodicamente o uno.]
    {\includegraphics[width=.45\linewidth]{gfx/example_3}} \quad
    \subfloat[Titulo debitas.]
    {\includegraphics[width=.45\linewidth]{gfx/example_4}}
    \caption[Tu duo titulo debitas latente]{Tu duo titulo debitas
    latente.}\label{fig:example}
\end{figure}
