子浮动之间的垂直图标

Question

你好，我想做的是在子浮动图像之间添加图标（例如箭头），以显示图像之间的某种“过程”。

这是我目前的代码：

\documentclass{report}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subfig}

\begin{document}

\begin{figure} [h]
  \subfloat[text 1]{
     \includegraphics[width=0.28\textwidth]
     {example-image-a}}
      \hfil
  \subfloat[text 2]{
     \includegraphics[width=0.28\textwidth]
     {example-image-b}}
      \hfil
  \subfloat[text 3]{
     \includegraphics[width=0.28\textwidth]
     {example-image-c}}

  \subfloat[text 4]{
     \includegraphics[width=0.28\textwidth]
     {example-image}}
      \hfil
  \subfloat[text 5]{
     \includegraphics[width=0.28\textwidth]
     {example-image}}
      \hfil
  \subfloat[text 6]{
     \includegraphics[width=0.28\textwidth]
     {example-image}}

  \captionof{figure}[]{long text}
  \label{fig:merge}
\end{figure}

\end{document}

这给了我这个：

我想要的是：

有办法吗？
