Incorrect reference to figure: the role of caption and centering

Recently I wrote a document structured mostly as a bullet point and with a lot of figures.
Everything went fine except that occasionally the figures would be referred with the wrong number, altough no mistake was made in the code.
A part the already known problem of putting the label -after- the caption, it turned out that the responsable was also the \centering, by somehow messing up with the labeling system.
The solution is to use the center environment as a replacement of \centering (here demonstrated with multiple figures):

\begin{figure}[!ht]

\begin{center}

\subfigure[]{

\includegraphics[width = 0.4\textwidth]{figures/ImageA.JPG}}%

\subfigure[]{

\includegraphics[width = 0.4\textwidth]{figures/ImageB.JPG}}%

\\

\subfigure[]{

\includegraphics[width = 0.4\textwidth]{figures/ImageC.JPG}}%

\subfigure[]{

\includegraphics[width = 0.4\textwidth]{figures/ImageD.JPG}}%

\caption{Some caption.}

\end{center}

\label{SomeLabel}

\end{figure}

Problem solved!
