[l2h] using includegraphics[] with image files having same names but in different folder?

I'll try to make a small example to show the problem, but I need time since 
this is a large tree and large tex file. But all the graphics including code 
looks like this:

\begin{center}
\includegraphics[]

{e1/matlab/e1.png}

\end{center}



....



\begin{center}

\includegraphics[]

{e1/maple/e1.png}

\end{center}



I actually spent the last 6 or so hrs changing all the file names and the 
tex file making the names of the images unique. So the problem now do not 
exist. But I can reproduce it again.

Ok. Thanks for this info.

It starts like this
\documentclass[12pt]{article}%
\usepackage{html}

\usepackage{amsmath}

\usepackage{amsfonts}

\usepackage{amssymb}

\usepackage{graphicx}



Then just lots of



\section{bla bla}

\section{bla bla}

\section{bla bla}



etc...



and inside each section is where I include the images, with same name, but 
from different folders.

Yes. inside EACH section, I do
\begin{center}
\includegraphics[]

{e1/matlab/e1.png}

\end{center}



....



\begin{center}

\includegraphics[]

{e1/maple/e1.png}

\end{center}


Where in the above, "e1" corresponds to section "1". And I have folders 
called "e1" , "e2" , etc....
So within a section, the image names will be the same, but in different 
folders.
