["Egor Tur" <worldeb@ukr.net>]

Hi Debian community!
I have little quesion about usage of LaTeX.
I want to place very many graphics in my doc , but when translate the tex file
in dvi and ps,  I see that my graphics place on end of file. What  should I do
that my graphics place correct . I use graphicx package and \begin{figure}[h] (and [H], [ht], [Ht]) command.
Where do the configuration files of tetex distributive locate? Is it  /etc/texmf/?
Thanx.
