\section*{Introduction}

This document is intended to check the support of picture inclusion using 
\verb|\includegraphics|. Only options \texttt{width} and \texttt{height} are 
supported. The file name or path may include spaces. The file path can be 
specified with \verb|\graphicspath|. In general, file extensions can be 
omitted. However, with case-sensitive file-systems (like under Linux), files 
with extensions in upper-case cannot be omitted.

\begin{matching}[dd]{Picture}
\includegraphics{1 1.PNG}
% on Linux, if .PNG is omitted moodle tries to manipulate "fig/1 1.png"
