在 beamer 中的每个部分幻灯片中添加不同的图像

Question

我在 Beamer 中使用 Metropolis 主题，需要在每个部分添加不同的图像。当然，我也想保持进度条原样。我正在使用此代码，但不幸的是，它不起作用。

       \documentclass[10pt]{beamer}
\usetheme[progressbar=frametitle]{metropolis}
\usepgfplotslibrary{dateplot}
\usepackage{xspace}
\newcommand{\themename}{\textbf{\textsc{metropolis}}\xspace}
\usepackage{xcolor}
\usepackage{graphicx,array}
\usepackage{tikz}
\usepackage{xcolor}
\usepackage[utf8]{inputenc}
\usepackage{transparent}

\definecolor{darkmidnightblue}{rgb}{0.0, 0.2, 0.4}

\begin{document} 
\maketitle

    \begin{frame}{\textbf{1st frame example}} %several frames (slides) like this one
    In this lecture we will:
    \begin{itemize}
        \item Introduce...
        \item Define ...
        \item Explore ...
        \end{itemize}
    \end{frame}  

%section 1 with image 1 I also need the image to be transparent
     \section{\textcolor{darkmidnightblue}{\textbf{Measuring Inequality}}}
       \transparent{0.4}\includegraphics[height=2cm]{section_1_image.png}

    \begin{frame}{\textbf{2nd frame example}} %several frames (slides) like this one
    In this lecture we will:
    \begin{itemize}
        \item a
        \item b
        \item c
        \end{itemize}
    \end{frame}  

%section 2 with image 2 I also need the image to be transparent
     \section{\textcolor{darkmidnightblue}{\textbf{Measuring Poverty}}}
       \transparent{0.4}\includegraphics[height=2cm]{section_2_image.png}

  \begin{frame}{\textbf{3rd frame example}} %several frames (slides) like this one
    In this lecture we will:
    \begin{itemize}
        \item d
        \item e
        \item f
        \end{itemize}
    \end{frame}  

%section 3 with image 3 I also need the image to be transparent
     \section{\textcolor{darkmidnightblue}{\textbf{the summary}}}
       \transparent{0.4}\includegraphics[height=2cm]{section_2_image.png}

 \begin{frame}{\textbf{summary}}{}
    Today, we have:
    \begin{itemize}
        \item Introduced...
        \item Defined ...
        \item Explored ...
        \end{itemize}
    \end{frame} 

\end{document}

你能帮忙吗？谢谢
