[Tex/LaTex] Insert set of images in latex

graphicssubfloats

I have a processus that I would represent it by a set of images like the below image. How can do this using the subfigure package?

This arrangement doesn't require anything special. Here's such an arrangement inside a figure that doesn't use any sub-figure package. Elements are not referenceable though (that can be changed, if needed):

enter image description here

\documentclass{article}
\usepackage{graphicx,array}
\newcommand{\subfigANDtitle}[2][.2\linewidth]{%
  \begin{tabular}{@{}>{\centering\arraybackslash}p{#1}@{}} #2 \end{tabular}}
\begin{document}

\begin{figure}
  \centering
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}

  This is a long title A.

  \medskip

  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}

  This is a long title B.

  \medskip

  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}\hfill
  \includegraphics[width=.2\textwidth]{example-image}

  This is a long title C.

  \medskip

  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title A} \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title B} \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title C} \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title D}

  \medskip

  \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title A} \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title B}
  \hfill\mbox{}

  \medskip

  \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title C} \hfill
  \subfigANDtitle{\includegraphics[width=.2\textwidth]{example-image} \\ title D}
  \hfill\mbox{}
\end{figure}
