In order to give my memoir based book a more professional look, I disabled the printout of chaptername, chapternumber and chapter title via the commands
\renewcommand{\printchaptername}{}
\renewcommand{\printchapternum}{}
\chapter[TOC title][Header Title]{}
and in the beginning of each file I used the command
\begin{center}
\includegraphics[width=\textwidth]{chapterTitle.eps}
\end{center}
where chapterTitle.eps was a figure saying for example
CHAPTER 1 INTRODUCTION
with the appropriate colors and positioning of the strings. Is it possible to do the same thing with the TOC, namely to disable the printing of
\contentsname
and display a figure-based version of it? I think that this would give to the TOC a more professional appearance
