I'm pretty sure you know the following already: but what Org does, when making math-pngs for HTML, is to generate tex files that are processed with dvipng (as far as I remember). Since a while ago amsmath is a default package in Org so a ox-html solution would also be able to work with png files. The patch that I posted somewhere else isn't tested with pngs yet, but it will be. > I'm not a mathematician but I read many books on mathematics and > theoretical physics (I'm a physicist) and don't remember examples of use > an equation with a caption.

I have seen framed boxes some times, and even floats, but never caption. I never attested to the usefulness of equation-captions. Though, I'm sure you would agree that Org should produce valid TeX files. > Again, this was my IMHO.
