creating png images from latex

Recently at work i had to generate images from latex equations. I used Miktex latex suite to generate the images. Here is the template i used for generating the images.

== Preamble ==
\documentclass[11pt]{article}
\newenvironment{custommargins}[2]%
{\addtolength{\leftskip}{#1}\addtolength{\rightskip}{#2}}{\par}
\pagestyle{empty}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{hyperref}
\usepackage{mathptmx} % rm & math
\usepackage[scaled=1.0]{helvet} % ss
\usepackage[papersize={5.75in},top=1pt,bottom=1pt,left=5pt,right=1pt]{geometry}
\begin{document}
\begin{custommargins}{-2cm}{-2cm}
\begin{flushleft}

== Your equation latex snippet ==

== Postable ==

\end{flushleft}
\end{custommargins}
\newpage
\end{document}

Steps to create image
1) Create a tex file using the above template
2) Create a DVI file using - $LATEX_PATH --quiet --interaction=nonstopmode $temp_tex_file_name
3) you may need to run it twice for formulas to render properly
4) Create png image using - $DVIPS_PATH -q $tmp_filename.dvi -o $tmp_filename.png


You are done!!
