... on second thought, maybe  it would be an even better idea to just
define a new "submit" like input type that would submit the form as soon
as it's fully loaded and display the POST result as an image. This would
work better with the form metaphor and would present less security
risks, since only very few sites allow <form> or <input> elements in
user content.

Martin Janecke's example would then look like this:

<form method="post" action="http://www.forkosh.dreamhost.com/mathtex.cgi">
<input type="hidden" name="latexdata" value="\begin{align} (... latex
...) \end{align}">
<input type="post-image">
</form>
