# How do I suppress the counter for figures?

I am including some illustrations in the figure environment so that they float properly and so I can caption them, but I don't want the counter. Is there a way to suppress this?

\documentclass{memoir}

\usepackage[demo]{graphicx}
\usepackage{float}

\newfloat{illustration}{thp}{lop}

\begin{document}

\begin{illustration}
\begin{center}
\includegraphics[width=3.5in,height=5in]{image001}
\caption{{\large \textbf{Caption}}}
\end{center}
\end{illustration}

\end{document}

memoir offers also the command newfloat you don't need the package float. –  Marco Daniel Apr 27 '12 at 21:27

The whole answer refers the documentation of memoir:

CTAN memoir

You are using memoir. memoir provides also the command \newfloat So you don't need the package newfloat. See section 10.1 NEW FLOAT ENVIRONMENTS

What you want is called by memoir legend. So the command \legend helps you.

In the documentation you can find:

The \legend command is intended to be used to put an anonymous caption, or legend into a float environment, but may be used anywhere.

-

You could load the caption package and use the starred version \caption*. (The package is also useful for formatting the caption.)

\documentclass{memoir}

\usepackage[demo]{graphicx}
\usepackage{float}

\newfloat{illustration}{thp}{lop}

\usepackage[font={large,bf}]{caption}

\begin{document}

\begin{illustration}
\begin{center}
\includegraphics[width=3.5in,height=5in]{image001}
\caption*{Caption}
\end{center}
\end{illustration}

\end{document}

The caption package seems to break memoir somehow. –  Jeremy Apr 27 '12 at 22:53
@Jeremy: please be more explicit. If you don't provide any concrete information it's almost impossible to guess what the problem might be. You can edit your question and add a MWE showing the problems you are having with the caption package. –  Gonzalo Medina Apr 27 '12 at 23:16
The caption package should not break memoir as such, but you do need to remember that the caption package replace all of the memoir captioning interfaces, so you will need to use the caption package equivalents. –  daleif Apr 28 '12 at 9:56
