Graphics, Figures & Tables ⇒ Span a Figure over two Pages

[mirou]

Hello TeX friends,

I am using Latex and doing my thesis in memoir class.
I have been able to use the \twopagepicture to span a process map over tow opposite pages in my chapter. However, my figure is reproduced at the end of the chapter not under its relative section.

In my chapter here is the code

Code: Select all

\chapter{Cas Pilote:}
\label{chap:Pilote}
\minitoc
\section 
text text text
\twopagepicture{b}{p}{Chapitre8/processmap.jpg}{processus}\label{fig:ATMprocess}
\section
text text text
\end

Im my formats and styles definition file I have the following code:

Code: Select all

\usepackage{amsmath,amssymb}             % AMS Math %Format& definition of styles Myriam
\usepackage[french]{babel}
\usepackage[latin1]{inputenc}

Can anyone help me find a command that would force Latex to produce the figure at the first available even page and not wait until all the chapter is over (40 pages!!!).
Notice that I have used \clearpage and \cleardoublepage but both have absolutely no effect on the positioning of the figure.
Thanks
