\begin{itemize}
\item Make sure your images are named as \texttt{<filename>-<x>.<format>} where \texttt{x} is the sequence number.
\item By default, \texttt{x} starts from 0, but you can specify a custom starting number.
\item Example: \texttt{fig-0.png}, \texttt{fig-1.png}, \texttt{fig-2.png},\ldots
\item The following example uses 8 images named as \texttt{Draw-a-Cat-Face-Step-1.jpg}, \texttt{Draw-a-Cat-Face-Step-2.jpg}\ldots
