I want to insert png files into my document.

basically, like this, it works (after invoking ‘float’),

\begin{figure}[H]
  \begin{center}
      \includegraphics{myfigure}
    \caption{short caption}{VERY LONG FIGURE LEGEND}
    \label{fig:myfigure}
  \end{center}
\end{figure}

but like that, it doesn’t,

\begin{figure}[htbp!]
  \begin{center}
      \includegraphics{myfigure}
    \caption{short caption}{VERY LONG FIGURE LEGEND}
    \label{fig:myfigure}
  \end{center}
\end{figure}

which is weird to me; obviously I invoke \usepackage{graphicx} as well since without that it wouldn’t work in the first place. Any suggestions what the problem could be?

UPDATED: found the solution:

I had defined the \textsuperscript macro as in http://anthony.liekens.net/index.php/LaTeX/SubscriptAndSuperscriptInTextMode

a fix is sketched in Figures occurring after ^ and _ macros (was: LaTeX limitation?), and it seems to work for me

cheers!!
