PM authors have used various markup conventions for inserting figures. Figure out what is being used, and write code that will adjust their TeX files so that each figure has a proper \begin{figure}… \end{figure} environment thrown around it. Submit diffs to authors.
For the long term, appropriate figure environments should be part of the PM style guide.
Drini has been wroking on the business of inserting pictures. As I understand it, there are still a few issues that haven't been completely sorted out to make the pictures come out right (or maybe they have been solved by now, I certainly know that he ws still morking on them a few weeks ago.) Also, he is writing a giude to PM graphics which will presumably discuss this. --rspuzio
Notice also that what I use and what I've seen most people also uses is
\begin{center}
\includegraphics{file}
\\Possibly some caption, seldom used
\end{center}--drini
\newcommand{\figura}[1]{\begin{center}\includegraphics{#1}\end{center}}
\newcommand{\figuraex}[2]{\begin{center}\includegraphics[#2]{#1}\end{center}}where the second is a "extended" version that lets me pass parameters to includegraphics. I don't think my solution is optimal, however --drini
