I recently read the post about insets (Image inside another image) and am trying to implement the method that uses overlaps. I can get the inset to appear, but I can't figure out how to position it. My LaTeX looks like this:
\begin{figure}[h]
\centering
\includegraphics[scale=0.9]{figure2_2.eps}\llap{\includegraphics[height=2cm]{inset_f2_cropped.pdf}}
\caption{words}
\label{f2}
\end{figure}
The inset shows up in the lower left, mostly outside of the actual figure; I am a relatively new user, so if this is just the result of misinterpreting the original answer, I'm sorry!
