\begin{frame}{Columns}
Here are three MUN logos which are all resized to fit inside
their respective columms.  This uses the \texttt{columns} environment of Beamer:

\vfill
  \begin{columns}[t]
    \begin{column}{0.4\textwidth}
      Text for column number 1.  This has a large logo.

      \bigskip
      \includegraphics[width=\textwidth]{MUN_Logo_RGB.png}
    \end{column}

    \begin{column}{0.3\textwidth}
      Text for column number 2.  This has a medium size logo.

      \bigskip
      \includegraphics[width=\textwidth]{MUN_Logo_RGB.png}
    \end{column}

    \begin{column}{0.2\textwidth}
      {\footnotesize Text for column number 3.  This has the smallest logo.}

      \bigskip
      \includegraphics[width=\textwidth]{MUN_Logo_RGB.png}
    \end{column}
  \end{columns}

\vfill
Make sure that the column widths do not total more that one full \texttt{$\backslash$textwidth}.
