How to create horizontal columns in Beamer?

Question

I'm creating a Beamer presentation, and I want a slide that has the following format:

figure -> some itemization -> figure

So on the far left I want to have an image, then some itemization next to the figure, and then on the far right another figure. So itemization is between two figures. But, I want to have three of these in one slide, one under the other. So I want to have three horizontal column, each having the above format.

I know the \begin{column} thing, but it creates vertical columns. I need horizontal ones. Any idea how to achieve this? Currently, I have just just this:

\documentclass{beamer}
\begin{document}

\begin{frame}{MD}
\begin{figure}
\includegraphics[scale=0.5]{pkc}
\end{figure}
\begin{figure}
\includegraphics[scale=0.5]{skc}
\end{figure}
\begin{figure}
\includegraphics[scale=0.5]{protocols}
\end{figure}
\end{frame}

\end{document}

It just loads the three figures one under the other correctly, but they are not in the far left of course, but in the middle. And I don't know how to achieve this horizontal columns. Any ideas?

Is this the layout you are looking for?

\documentclass{beamer}
\begin{document}

\begin{frame}
\frametitle{MD}

\begin{columns}
    \begin{column}{.3\textwidth}
        \includegraphics[width=.7\textwidth]{example-image} 
    \end{column}
    \begin{column}{.3\textwidth}
        \begin{itemize}
            \item item 1
            \item item 2
            \item item 3
        \end{itemize}
    \end{column}
    \begin{column}{.3\textwidth}
        \includegraphics[width=.7\textwidth]{example-image} 
    \end{column}
\end{columns}
\vfill
\begin{columns}
    \begin{column}{.3\textwidth}
        \includegraphics[width=.7\textwidth]{example-image} 
    \end{column}
    \begin{column}{.3\textwidth}
        \begin{itemize}
            \item item 1
            \item item 2
            \item item 3
        \end{itemize}
    \end{column}
    \begin{column}{.3\textwidth}
        \includegraphics[width=.7\textwidth]{example-image} 
    \end{column}
\end{columns}
\vfill
\begin{columns}
    \begin{column}{.3\textwidth}
        \includegraphics[width=.7\textwidth]{example-image} 
    \end{column}
    \begin{column}{.3\textwidth}
        \begin{itemize}
            \item item 1
            \item item 2
            \item item 3
        \end{itemize}
    \end{column}
    \begin{column}{.3\textwidth}
        \includegraphics[width=.7\textwidth]{example-image} 
    \end{column}
\end{columns}

\end{frame}
