I'm writing with the LNCS template on Overleaf, and there's a rather wide figure I need to put on (illegible if made narrower). Because the left side is be lined up with the text, the \centering command doesn't work anymore, and it turns out to look like the following:

Is there a way to break the left-lineup and center the figure without changing its width (like where the yellow box is)? Thank you!
\centerline{\includegraphics[width=18cm]{3DQN.eps}}but absolutely should not unless you really have explored all other options. – Apr 27 '20 at 20:30\makebox[\linewidth]{\includegraphics[width=18cm]{3DQN.eps}}– Werner Apr 27 '20 at 20:32
