[Tex/LaTex] Insert another slide between a pause in beamer

beamerpause

I would like to have in beamer something like

\begin{frame}
The two main reasons are : 
\begin{itemize}
\item First reason
\pause 
\item Second reason
\end{itemize}
\end{frame}

But I would like to insert an image to illustrate the first reason, that would be on another slide, without altering the display of my presentation.

I would therefore like to have

  • Slide n : slide a with first item shown
  • Slide n+1 : slide b with an image to illustrate this first item
  • Slide n+2 : slide a with the two items displayed

How would it be possible ? And additionnaly would it be possible for the slide b not to be numbered ?
