Can't make transparency work with white

Answering your points in order:

<ul><li>The reason you haven't heard of dBoard is that my master plan for taking over the discussion board universe is a bit behind schedule. I began working on it nearly a decade ago, but my day job keeps me from putting enough time into it, and I don't have any help, so I haven't released it yet. If you know of anyone just bursting at the seams with desire to work on YABB (that name is taken, by the way), steer them my way. I started on it before many had heard of PHP, and so it is written in Perl. In my day job I use C++.

If you really think anyone would find Perl code helpful I could post it, let me know, but it's nothing any Perl coder couldn't figure out.

<li>No, the forum doesn't link to your equation editor.

<li>The forum runs on an Intel dual-core machine running Centos 5.2. I support several websites, but the discussion board is the only one with significant activity, perhaps 150 messages/day and bandwidth of maybe 30 GB/month on average, so there's plenty of spare cycles. I'd be glad to help you guys out as long as there's no significant time investment on my end, just let me know.</ul>

Thanks for the diagram example, I posted it at the forum. I notice your board puts up a hoverbox with the Latex text, I should do the same.

Added by Edit: I'm getting feedback from some members that .png's don't work with IE 6. I'm sticking with .png's, but will investigate whether I can rig IE's AlphaImageLoader to step in when IE 6 is detected.
