Alright, I think I finally got what your problem is. Your picture's URL
is by no means unknown. The URL is always this:
http://www.forkosh.com/mathtex.cgi?formdata=blah
.... where formadata is a GET parameter that contains the raw LaTeX code.
You can compose the actual URL with rawurlencode(). E.g.:
$latex = '\Large f(x)=\int_{-\infty}^x e^{-t^2}dt';
$url = 'http://www.forkosh.com/mathtex.cgi?formdata=' .
rawurlencode($latex);
Once you have the URL, you could download it with many PHP functions,
including the ones you've been evaluating, but you don't really need to.
You just have to use the <img> tag in an HTML document and the browser
will download it for you:
<img src="<?php echo htmlspecialchars($url); ?>">
