不使用\titlegraphic宏，你可以将图像放在包含标题页的框架的开头：

\documentclass{beamer}
\usetheme{Copenhagen}
\usecolortheme{beaver}

%no navigation symbols
\setbeamertemplate{navigation symbols}{}
%no headline
\setbeamertemplate{headline}{}
%no footline
\setbeamertemplate{footline}{}
%insert frame numbering
\addtobeamertemplate{navigation symbols}{}{
    \usebeamerfont{footline}
    \usebeamercolor[fg]{footline}
    \hspace{1em}
    \large \insertframenumber/\inserttotalframenumber
}
%no frame number on the title frame
\AtBeginSection[]{
  \begingroup
  \setbeamertemplate{navigation symbols}{}
  \begin{frame}
  \frametitle{Outline}
  \tableofcontents[currentsection]
  \end{frame}
  \endgroup
}
%title frame does not count towards the numbering
\let\otp\titlepage
\renewcommand{\titlepage}{\otp\addtocounter{framenumber}{-1}}


%black title color
\setbeamercolor{title}{fg=black}
%black frame title color
\setbeamercolor{frametitle}{fg=black}



\author{Author\\[10mm]{\small Supervisor: Supervisor}}
\title{Title}
\institute{Institute}
\date{Date}
