# Remove the period at the end of the subcaption using \subbottom with memoir [closed]

I am using the memoir package (with hyperref package in case that makes a difference) and I am using \subbottom to place subfigures within a figure environment. I simply want the subcaptions to read (a) and (b), which is automatically handled, so I have left the caption empty (as shown below). However, the final output when I compile my code has a period after the (a) such that my figures are labelled (a). and (b). Any ideas on how to remove the period?

\begin{figure}[bt]
\centering
\subbottom[]{\includegraphics[width=0.28\textwidth]{imagea}\label{fig:imagea}}
\hfill
\subbottom[]{\includegraphics[width=0.30\textwidth]{imageb}\label{fig:imageb}}\\
\caption{Images}
\label{fig:images}
\end{figure}

Hi and Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – yo' May 9 '13 at 11:11
why not using th subcaption package? – Mario S. E. May 9 '13 at 11:21
Thanks for your help. I found my problem while trying to produce a minimum working example. The .sty file I am using had modified the default subcaption to `\@makesubfloatcaption{\@nameuse{@the#1}}{#3.}}'. Removing the full stop produced the desired effect. – felice May 9 '13 at 11:37
