changing background across sub-frames

[Lucio Chiappetti]

I have a frame, which consists of up to 6 sub-frames or overlays.
<1> to <3> have a common subtitle, while the rest of the content changes.
<4> has a different subtitle and content, and <5> and <6> yet another
title and varying content.

My convention wants to show the frame number in the frame title bar, but
not the subframe number ... a frame is a topic, while subframes are
subtopics.

So I am not considering the idea of splitting the frame in one frame
containing only <1> to <3> and another with <4> to <6>.

What I'd want to achieve is that sub-frames <1> to <3> (or even only
<1> to <2>) contain a different background.

My standard background is a solid black colour.
For <1> to <2> I'd like to show an image.

I can currently set such background and reset it to black using
\setbeamertemplate OUTSIDE of \begin{frame} ... \end{frame}.

Is there a way to reset the background to black INSIDE the frame (ideally
after <2>) ?

Or alternatively to display the image behind the text even if it is not
the "official" background ?



\pgfdeclareimage[width=128mm]{lssmosaic}{lssmosaic4}
\setbeamertemplate{background}{\pgfuseimage{lssmosaic}}

\begin{frame}[label=frameNames,t]
  \frametitle{LSSDB -- Nomenclature issues  -- \insertframenumber}
  \only<1-3>{
   \begin{beamercolorbox}[...]{some subtitle}\end{beamercolorbox}
   some stuff
  }
  \only<4>{
   \begin{beamercolorbox}[...]{some other subtitle}\end{beamercolorbox}
   some other stuff
  }
  \only<5-6>{
   \begin{beamercolorbox}[...]{yet another subtitle}\end{beamercolorbox}
   some more stuff
  }
\end{frame}

% reset the background
\setbeamertemplate{background}{}

Hi,
What about starting a new frame after <2> but keeping the same frame number?  You can do that  e.g. through

\addtocounter{framenumber}{-1}  

before the frame containing <3>.
