No caption number for figures and tables

Question

I want to make some of my figures just without a number.

Instead of Fig. 1: Caption. I want simply Caption.

I tried to do \caption*, but it doesn't work for me even after using the caption package upgrade.

Maybe there are another ways to do this?

Answer 1

You could use \captionsetup from the package caption that way:

\documentclass{article}

\usepackage{caption}

\usepackage{graphicx}

\begin{document}

\begin{figure}[h!]
\centering
\includegraphics[height=2cm]{figure}
\caption{Une figure.}
\end{figure}

\begin{figure}[h!]
\centering
\includegraphics[height=2cm]{figure1}
\captionsetup{labelformat=empty}
\caption{Une figure.}
% \addtocounter{figure}{-1} add this if you want the next figure to be numbered 2 
% otherwise it'll be numbered 3
\end{figure}

\end{document}

This gives:

Answer 2

You can also use \caption* when using the caption package which keeps only the caption title.

You may do something else what did not work, but this example works as desired:

\documentclass{article}
\usepackage{caption}
\usepackage[demo]{graphicx}
\begin{document}
\begin{figure}[ht]
\centering
\includegraphics{figure1}
\caption*{Caption.}
\end{figure}
\end{document}

Answer 3

I think the simplest way is to enter the caption not enclosed in the caption{} command.

MWE

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}
  \centering
  \includegraphics[width=0.5\textwidth]{Fig_test.png}
  \caption{This with float name and number}
\end{figure}
\begin{figure}
  \centering
  \includegraphics[width=0.5\textwidth]{Fig_test.png}\par
  This with just the caption
\end{figure}
\end{document}
