http://en.wikipedia.org/wiki/Help:Displaying_a_formulaCan I have a URL to show me what you are talking about?
Doesn't PHP have image creating/editing capabilities? Hence CAPTCHAs and the like. But I suppose it would be clunky to port Tex to something like PHP.Hmm, I know exactly what you are talking about.
Getting that on x10's free plan might be difficult.
I suggest getting a VPS so you can edit everything. That would be easiest however I have seen a way to make images using an external source. (e.g. http://blah.com/createteximage.php?code=$\frac{1}{2}=0.5$ )
Ok, thanks for your help, you have inspired me to Google your suggestion. And whatd'ya know:Yes, you have to pay for a VPS but with one, you could install this easily.
As I said, there is probably something that will create an image for you as I showed in the above example so you would put that code in image tags.
