	% Example

	% Add this at the beginning of the document (typically after the titlepage)
	\flstart

	% Then for each new figure you want to add, add the following
	\fladdfloat{%
		\begin{figure}[H]
			\includegraphics[scale=1]{Image1}
			\caption{Test}
			\label{Ima1}
		\end{figure}
	}

	% At the end of the document, to avoid a unwanted late terminated loop of empty page creation, add the following
	\flstop
\fi
