# Is it possible to flash a photo for a single slide in beamer?

I am hoping to show a tikzpicture that overlays the whole frame for a single slide without having to go in and add to every single other line that excludes the slide number I would like to have the picture show for. Is there a command to hide everything but one thing is a slide or overlay a picture for one slide and then have it disappear?

Thanks! I'm really not sure if it's possible and am already thinking I will likely need to do a lot of additions...

• I'm not sure to get it right but isn't beamer overlays what you're looking for? – Ivan May 28 '20 at 19:47

Sure. Here is one way to do it.

\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\begin{frame}[t]
\frametitle{Some title}
As you can see \only<.(1)>{\dots}%
\pause
\only<.(1)>{\begin{tikzpicture}[overlay,remember picture]
\node[outer sep=0pt,inner sep=0pt] at (current page.center)
{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-duck}};
\end{tikzpicture}}%
\pause
even ducks do not put pineapple on a pizza.
\end{frame}
\end{document}


Please note that you do not need tikz to do that but it is really easy to get going with tikz.
