I've read above comments. I browsed l2tabuen.
I'm still confused.

I see how in my above quoted text the centering
of the image is superflous, since it wil be as
wide as the text anyway.

However, when the image is smaller, and I use

\begin{figure}
\centering
\gpicbox{graph}
\caption{some text}
\label{fig:some-fig}
\end{figure} 

The caption is centered, but the \gpicbox image is not.
when I use a centerline around it, the image does get
centered...
