### pgf missed package

Hi all,
I am working on a presentation using beamer and I would like to display a series of images with a specified delay. I found the following code:
\frame{\only<1>{\begin{centering}   \pgfimage[scale=.5]{fish1.jpg}   \par\end{centering}} \transduration<2>{5} \only<2>{\begin{centering}   \pgfimage[scale=.5cm]{fish2.jpg}   \par\end{centering}} \transduration<3>{5} \only<3>{\begin{centering}  \pgfimage[scale=.5cm]{fish3.jpg}  \par\end{centering}}}

I got a message error that I missed a required package.
Can anyone tell me the suitable package for that?
Thank you!
