I have the following code which doesn't align a) and b) with the top of the image. How can I align them?
...
\begin{enumerate}
\item Find the unknown values and in each case, give a reason.
\begin{enumerate}
\item
\includegraphics[scale=0.6]{images/image1.png}\\
\item
\includegraphics[scale=0.6]{images/image2.png}\\
\end{enumerate}
\end{enumerate}
...


\raisebox{-\height}{\includegraphics{...}or more simply use the facilities of theadjustboxpackage to change the baseline of the image. – David Carlisle Mar 10 '14 at 02:19
