Subfigs of a figure on multiple pages

Everything inside \begin{figure}...\end{figure} must not be larger than a single page. In order to break it over pages, you must do it manually. Use \ContinuedFloat from the subfig package to do this: (from the subfig documentation, §2.2.3)

\begin{figure}
  \centering 
  \subfloat[][]{...figure code...}% 
  \qquad 
  \subfloat[][]{...figure code...} 
  \caption{Here are the first two figures of a continued figure.}
  \label{fig:cont}
\end{figure}

\begin{figure}
  \ContinuedFloat 
  \centering 
  \subfloat[][]{...figure code...}% 
  \qquad 
  \subfloat[][]{...figure code...} 
  \caption[]{Here are the last two figures of a continued figure.}
  \label{fig:cont}
\end{figure} 

I know that this is an old thread, but I recently created the package figureSeries which may be a good answer here, you can find it at http://github.com/thomasWeise/figureSeries.

The package figureSeries provides

1. a facility to include an arbitrary number of (potentially differently-sized) sub-figures into a figure*-like construct,
2. the ability to make this figure*-like construct look as if it was a floating object, which
3. works well in both single-column and double-column documents.

This may sound odd, but why not put them in something like supertab to make them span several pages? You would get rid of the floating object "figure" which has to placed on one page completely - according to my knowledge.
