[Tex/LaTex] Making subfigures have captions like standard figures

subfloats

I have used subfigures to layout my figures in the way I would like, but I would like them to have captions as if they were standard figures. IE, Figure 1, Figure 2… Is there a way of doing this?

EDIT:
Here is how I am using subfigures.

\begin{figure}[htb]
\begin{center} \subfigure[Figure 1]{\includegraphics[width=\figwidth\textwidth]{1.png}}
\subfigure{\includegraphics[width=\figwidth\textwidth]{3.png}}\\
\subfigure{\includegraphics[width=\figwidth\textwidth]{4a.png}}
\subfigure{\includegraphics[width=\figwidth\textwidth]{4b.png}}
\end{center}
\end{figure}

Best Answer

If the sub-figures should get ordinary captions like "Figure 1" one could either use \captionbox offered by the caption package (which will align the sub-figures by their first caption line), or use \parbox or minipage with alignment parameter.

Example code:

\documentclass{article}
\usepackage[demo]{graphicx}
\newcommand\figwidth{0.4}

\usepackage{caption}

\begin{document}

\begin{figure}[htb]
\centering
\captionbox{}{\includegraphics[width=\figwidth\textwidth]{1.png}}
\captionbox{}{\includegraphics[width=\figwidth\textwidth]{3.png}}\\[2ex]
\captionbox{}{\includegraphics[width=\figwidth\textwidth]{4a.png}}
\captionbox{}{\includegraphics[width=\figwidth\textwidth]{4b.png}}
\end{figure}

\begin{figure}[htb]
\centering
\parbox[b]{\figwidth\textwidth}{%
  \includegraphics[width=\hsize]{1.png}
  \caption{}}
% or \begin{minipage}[b]{\figwidth\textwidth}...\end{minipage}
\parbox[b]{\figwidth\textwidth}{%
  \includegraphics[width=\hsize]{3.png}
  \caption{}}\\[2ex]
\parbox[b]{\figwidth\textwidth}{%
  \includegraphics[width=\hsize]{4a.png}
  \caption{}}
\parbox[b]{\figwidth\textwidth}{%
  \includegraphics[width=\hsize]{4b.png}
  \caption{}}
\end{figure}

\end{document}

(Unfortunately \captionbox isn't documented yet but its syntax is identical to \subcaptionbox documented within the subcaption package documentation.)
