Beamer – How to Show Images Step by Step in the Same Location

beamer

I'm trying to show images step by step at the same location. This is my code:

\documentclass[xcolor=dvipsnames]{beamer}

\begin{document}
\section{Approach}

\begin{frame}{Approaches}
\only<1->{
Hello, world.
}

\only<2>{
   \begin{figure}[ht]
       \includegraphics[width=5cm]{pic/intro2.pdf}
    \end{figure}
 }
\only<3>{
   \begin{figure}[ht]
       \includegraphics[width=5cm]{pic/intro3.pdf}
    \end{figure}
 }

\end{frame}

\end{document}

The issue is that the texts (Hello, world) varies in its location for each slide.
How can I fix the location?

When used with \visible command, the texts are located in the same locations, but this is not what I expect as I want to have the diagrams at the same location also.

    \begin{overlayarea}{5cm}{4cm} % your height
     \includegraphics[width=2cm]<2>{1.jpg}
     \includegraphics[width=2cm]<3>{3.jpg}
     \end{overlayarea}
\end{figure}

Bouh !
\end{frame}

Beamer – How to Show a Frame Step by Step

beamer provides \pause that provides this functionality. You can add that anywhere in the slide and it will "pause" the output there, produce an additional slide for post-pause display.

Additionally, many commands typical to LaTeX have been modified in beamer to provide a so-called overlay specification. As an example, the following list show each item only on the specified slides:

\begin{enumerate}
  \item<1-> First item
  \item<2> Second item
  \item<3> Last item
\end{enumerate}

Here, the overlay specification is contained within < >. Slide 1 will contain only the "First item". Slide 2 will contain "First item" and "Second item". Slide 3 will contain "First item" and "Last item". This example, taken from the front page of the package documentation provides another view on overlay specifications:

\begin{frame}
  \frametitle{There Is No Largest Prime Number}
  \framesubtitle{The proof uses \textit{reductio ad absurdum}.}
  \begin{theorem}
    There is no largest prime number.
  \end{theorem}
  \begin{proof}
    \begin{enumerate}
      \item<1-| alert@1> Suppose $p$ were the largest prime number.
      \item<2-> Let $q$ be the product of the first $p$ numbers.
      \item<3-> Then $q+1$ is not divisible by any of them.
      \item<1-> Thus $q+1$ is also prime and greater than $p$.\qedhere
    \end{enumerate}
  \end{proof}
\end{frame}

The display depends on the theme used. Below is the first slide of the above frame code from two different themes (left: default; right Frankfurt):

There are many slide overlay specifications possible. Review the package documentation to see the format provided with each command/environment.

It's possible to loop over the images of course, for example, with \foreach from pgffor.

\documentclass[draft]{beamer}

\usepackage{pgffor}

\begin{document}

\begin{frame}
    \frametitle{Title}
    \framesubtitle{Subtitle}
    \centering
    \foreach \x in {1,...,5} {%
    \includegraphics<\x>[scale=0.5]{a_\x.jpg}%
    }
\end{frame} 
\end{document}
