A couple of possible approaches using ImageMagick:

1. A simple bash script:

/usr/bin/latex --interaction=batchmode temp.tex
/usr/bin/dvips -E temp.dvi -o temp.ps
/usr/bin/convert -density 120  -trim -transparent "#FFFFFF" temp.ps image.png

applied to temp.tex:

\documentclass[10pt]{article}
\usepackage[latin1]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\pagestyle{empty}
\begin{document}
$formula goes here$
\end{document}

and the result is image.png containing whatever formula is put in temp.tex

2. Use a PHP page on the net where the students input the code and the image is then produced for copying. See
http://www.artofproblemsolving.com/LaTeX/AoPS_L_TeXer.php for an example and the demo folder of the LatexRender download
at http://www.mayer.dial.pipex.com/tex.htm for the code.
