Take the 2-minute tour ×  I am trying to compose an exam with a
figure as part of the question. However, I am having trouble
using the standard \includegraphics command with pdflatex. I can
not specify the arguments to \includegraphics in the square
brackets. If I remove the square bracket (optional arguments),
then it compiles without issue. I've tried wrapping it in the
\fullwidth{} command to no avail.  Here is a minimal example:
\question[] True/False questions. \part[2] True or
False.\vspace*{1in} An image:  share|improve this question A
general comment: Using \linewidth instead of \textwidth might be
more appropriate. The reason for this is that \textwidth may be
fixed across your entire document, while \linewidth may vary,
depending on the environment you're in. For example, in
enumerate or itemize (typical for question-style documents like
an examination), the \linewidth is smaller than \textwidth (due
to the added indent). This leads to a better horizontal fit on
the page. –  Werner Oct 1 '11 at 0:0
