I have an initial implementation ready of the [latex] code, this is my first test trying the same binomial equation:
$\color{white} \frac{-b\pm\sqrt{b^2-4ac}}{2a}$
How about a simple $\color{white} y = mx + b$ inline equation, how's that look?

A bit of basic string theory
$\color{white} I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
$\color{white} La{\tau\epsilon\chi}$
Ink weight is a bit heavy - can that be changed?

Re: A bit of basic string theory
I wasn't happy with that either and already had inquiries in. The problem seems to be that the graphical renderer assumes a white background, and so the text is dithered with that assumption.
In the meantime, here's another way to say Latex:
$\color{white} \color{yellow}\LaTeX$

Testing a variation...
Current:
$\color{white} \frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{white} I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
A couple variations using old rendering approach:
$\fg_f2ffff \fn_jvn \95dpi \frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\fg_f2ffff \fn_cm \100dpi I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$

What are you using to render the Latex, Percy?

Another Variation
$\fg_f2ffff \300dpi \frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\fg_f2ffff \300dpi I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
Okay, this looks pretty good, but I'll have to have Javascript code explicitly set the image widths according to some predetermined scale.

Yet Another Variation
Got an answer back from CodeCogs, giving it a try with both non-bold and bold, and with white and red:
$\color{white}\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\bf\color{white}\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{red}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
$\bf\color{red}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
Excellent!

Re: Yet Another Variation
On this one, I see a lot of dots and vertical lines.
I'm using IE 6.0 at work here.
The one above the one I'm replying to, where you mention getting Java to set the default size or whatever was much smoother and clearer.

Updated Latex Rendering
This is the newest Latex rendering approach, please let me know if you see any problems.
$\color{white} \frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{white} I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
Same thing in yellow:
$\color{white} \color{yellow}\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{white} \color{yellow}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
Same thing in red:
$\color{white} \color{red}\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{white} \color{red}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
Same thing in green:
$\color{white} \color{green}\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{white} \color{green}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$
Same thing in bold green with Verdana font:
$\color{white} \fn_jvn \bf\color{green}\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$\color{white} \fn_jvn \bf\color{green}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$

Re: Updated Latex Rendering
stupid question #1946576
How long did it take you to do the following:
$\color{white} \color{green}I=\int_{\cal{B}}d^4\! x\sqrt{\tilde{g}} e^{\Phi}\left(\tilde{R}(\tilde{g})+\left(\nabla \Phi \right)^2-{1\over 12} H_{\mu\nu\rho}H^{\mu\nu\rho} \right)$

Independent confirmation
I'm using IE 6.0 at work here.
Same here and it looks all broken up and 'dotty' for me too.

Same again here, when I switch to IE 6.0
