In article <1992Sep1.150736.5707@irisa.fr>, I write:

Thanks to Donald Arseneau <asnd@erich.triumf.ca> for his answer:
using something similar to \pageref

\def\floatpagenum#1{\@ifundefined{r@#1}{{\relax}\@warning
   {Reference `#1' on page \thepage \space
    undefined}}{\edef\@tempa{\@nameuse{r@#1}}
   \edef\thispage{\expandafter\@cdr\@tempa\@nil\space}%
   \ifx\thispage\space\def\thispage{0 }\fi %
}}

\begin{figure}[p]
\floatpagenum{mylabel} % setting the value of \thispage
\ifodd\thispage
 <...>
\else
 <...>
\fi
\caption{...}\label{mylabel}
\end{figure}
