Notes

To put two figures side by side you can use minipages inside the figure environment.

\begin{figure}[t]
\begin{minipage}[t]{0.48\textwidth}
\begin{center}
\includegraphics[width=0.92\textwidth]{images/picture1}
\caption{\label{fig:pic1}Caption 1}
\end{center}
\end{minipage}
\hfill
\begin{minipage}[t]{0.48\textwidth}
\begin{center}
\includegraphics[width=0.92\textwidth]{images/picture2}
\caption{\label{fig:pic2}Caption 2}
\end{center}
\end{minipage}
\end{figure}
