[texhax] placing graphics in latex in exactly a given position in the text

[Alessandro Bernardini]

how can i force latex to place a graphic (figure in a pdf file) exactly in a
given position, before the text continues ?

with the command
\begin{figure*}[h]
\includegraphics{myfigure.pdf}
\end[figure*}

written text.

it can happens that "written text" is displayed before teh figure, who is
displayed in the next page.
I want the figure exactly before "written text", even when a pagebreak
occurs.

If the figure is splitted on two pages it is ok or even better...

The figure should not be numbered (figure*).
