Beamer: How to show images as step-by-step images

Question

I'm trying to make a presentation using the Beamer class. I want to show a simple list of images, one by one in one frame, just like when you use itemize<+->.

I have no problem showing the images one-by-one, but the images shifts every time I insert a new image. How do I solve this - From my perspective there must be a simple solution, without specifying the absolute placement of the images.

Would you like to show all the images in a single frame, or each image in its own frame, but aligned with the images shown before? – Carder

In a single frame... So the images do not shifts as they are uncovered – Nuts

You can find an entire community on the TeX StackExchange, where no TeX-related question is too small. See this question. – Hagride

Thanks for the link! I didn't know that existed. – Nuts

Answer 1

I found a solution to my problem, by using the visble-command.

EDITED:

\visible<2->{
   \textbf{Some text}
   \begin{figure}[ht]
       \includegraphics[width=5cm]{./path/to/image}
    \end{figure}
 }

visible is superior to onslide when it comes to figures, because onslide tries to transparentize a figure, but it cannot! – Wieland

I think it is not needed to use \begin{figure} in most cases like this. You can just put the \includegraphics part, at least that is what I prefer. Do you intend to have numbered figures in a beamer slideshow? If yes, you are more fastidious than I :) – Mesics

Nice solution, as space for figure will be taken into account in previous overlays, while it does not seem to be the case with the \includegraphics<1>{A} approach. Worth emphasising in your post? – Ellen

It worked perfectly for my case: 3 images with space between each other (\hfill-IMG1-\hfill-IMG2-\hfill-IMG3-\hfill). All the other solution makes the images move. – Heteronomy

Answer 2

You can simply specify a series of images like this:

\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}

This will produce three slides with the images A to C in exactly the same position.

I also tried this with some success, but instead of "popping up", I would rather have the content allocated on the frame from the start. This is makes the other content on the slide move, when it appears. – Nuts

This one doesn't work if the images are individually wrapped in centerline. If they're all wrapped in a single centerline then it works. – Tompion

Put a % at the end of each line such that the images don't move (See Subhadeep's post below) – Wreckfish

Answer 3

\includegraphics<1>{A}%
\includegraphics<2>{B}%
\includegraphics<3>{C}%

The % is important. This will keep all the images fixed.

Unspent

Shouldn't this be a comment to Svante's answer? – Mokpo

I found the '%' essential for keeping the images fixed; is it a beamer-specific of latex-generic feature? – Bodhisattva

@Bodhisattva I suspect that this is LaTeX-wide. The percentage sign tries to get rid of an extra whitespace that would be there due to the newline character. In most situations the extra whitespace is helpful, e.g., mid-sentence line break. In this case it's a nuisance. – Avaria

Isn't % supposed to start a comment? Why does it change the content here? – Tholos

Answer 4

This is what I did:

\begin{frame}{series of images}
\begin{center}
\begin{overprint}

\only<2>{\includegraphics[scale=0.40]{image1.pdf}}
\hspace{-0.17em}\only<3>{\includegraphics[scale=0.40]{image2.pdf}}
\hspace{-0.34em}\only<4>{\includegraphics[scale=0.40]{image3.pdf}}
\hspace{-0.17em}\only<5>{\includegraphics[scale=0.40]{image4.pdf}}

\only<2-5>{\mbox{\structure{Figure:} something}}

\end{overprint}
\end{center}
\end{frame}

Uncharitable

Answer 5

This is a sample code I used to counter the problem.

\begin{frame}{Topic 1}
Topic of the figures
\begin{figure}
\captionsetup[subfloat]{position=top,labelformat=empty}
\only<1>{\subfloat[Fig. 1]{\includegraphics{figure1.jpg}}}
\only<2>{\subfloat[Fig. 2]{\includegraphics{figure2.jpg}}}
\only<3>{\subfloat[Fig. 3]{\includegraphics{figure3.jpg}}}
\end{figure}
\end{frame}
