Right-Aligned Image with Pauses in Beamer

Question

See the end for code.

Let's say I have a frame in Beamer, and I want it to open with an image visible in a right column. I then want the text to appear with button presses (thus, pauses). How do I do this?

Below is example code of a left-aligned image that works perfect, but I need to move it to the right side:

\documentclass{beamer}
\mode<presentation> {
  \usetheme{Marburg}
  \usecolortheme{beaver}
  \setbeamercolor{author in sidebar}{fg = purple}
  \setbeamercolor{section in sidebar}{fg = white}
  \setbeamercolor{subsection in sidebar shaded}{fg = purple}
  \setbeamercolor{subsection in sidebar}{fg = pink}
  \useinnertheme{default}
}

\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{hyperref}
\usepackage{caption}
\usepackage{multicol}
\usepackage[none]{hyphenat}
\usepackage[english]{babel}
\usepackage{mathtools}
\usepackage{booktabs}
\usepackage{subcaption}
\usepackage{ulem}


\begin{document}
\begin{frame}
  \frametitle{Example}
  \begin{columns}

    \begin{column}{0.5\textwidth}
      \begin{figure}[H]
        \includegraphics[width = \linewidth]{example-image-a}
        \caption{EXAMPLE A}\pause
      \end{figure}
    \end{column}
    
    \begin{column}{0.5\textwidth}
      \begin{itemize}
      \item Item 1\pause
      \item Item 2\pause
      \item Item 3
      \end{itemize}
    \end{column}
    
  \end{columns}
\end{frame}

\end{document}

Answer 1

You don't need a column environment within the columns environment. You can use the \column command to create a new column. Subsequent columns will appear to the right of existing columns, so put the code for your list, then create a new column containing your figure. Also, you don't need a figure environment unless you specifically want the caption.

The \pause command is not limited to the columns environment, thus pauses everything thereafter. You have much better control using overlay specifications (see section 9 in the beamer documentation). Adding [<+->] after \begin{itemize} will increment the list (+) and keep items visible thereafter (-). This does not affect the other column containing the figure.

\documentclass{beamer}
\mode<presentation> {
  \usetheme{Marburg}
  \usecolortheme{beaver}
  \useinnertheme{default}
}

\begin{document}
\begin{frame}
\frametitle{Example}
\begin{columns}
\column{0.5\textwidth}
    \begin{itemize}[<+->]
    \item Item 1
    \item Item 2
    \item Item 3
    \end{itemize}
\column{0.5\textwidth}
    \begin{figure}[H]
    \includegraphics[width = \linewidth]{example-image-a}
    \caption{EXAMPLE A}
    \end{figure}
\end{columns}
\end{frame}
\end{document}
