# Caption for subfigures

I'm using the below script to display a figure. The problem is that I don't know how to put subcaption for each subfigure. I don't want to use any other packages. Any advice please?

\begin{figure}
\includegraphics[width=0.32\linewidth]{fig1.png}
\includegraphics[width=0.32\linewidth]{fig2.png}
\includegraphics[width=0.32\linewidth]{fig3.png}\\
\includegraphics[width=0.32\linewidth]{fig4.png}
\includegraphics[width=0.32\linewidth]{fig5.png}
\includegraphics[width=0.32\linewidth]{fig6.png}

\caption{big_caption.}
\label{label1}
\end{figure}

• Does tex.stackexchange.com/questions/132821/… help? May I ask why you don't want to use a package? Jul 12 '15 at 18:29
• @TorbjørnT. nope. As I want normal captions like (a),(b),...

• because in the conference I'm writing in they aren't allowing this. Any suggestions? I can try using other packages, and hope it will work

• If the conference doesn't allow any packages, it doesn't allow any packages. But take the example I linked to above, and remove \thefigure from \renewcommand\themysfig{\thefigure(\alph{mysfig})}. Or if you just need (a),(b) etc., you can perhaps add it in the pictures themselves. Jul 12 '15 at 18:36

If you don't want the subfigure captions to show up in the \listoffigures and you can remember the alphabet, you can use:

\documentclass{article}
\usepackage{mwe}% for images only
\begin{document}
\begin{figure}
\centering
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\par
\makebox[0.32\linewidth]{(a)}
\makebox[0.32\linewidth]{(b)}
\makebox[0.32\linewidth]{(c)}
\vspace{\baselineskip}\par
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\includegraphics[width=0.32\linewidth]{example-image}
\par
\makebox[0.32\linewidth]{(d)}
\makebox[0.32\linewidth]{(e)}
\makebox[0.32\linewidth]{(f)}
\vspace{\baselineskip}\par
\caption{big caption.}
\label{label1}
\end{figure}
