So eventually I tried this and indeed it works as expected. I have one more question though.

I've seen that most of the complex math formulas are converted into .png images with some long names - for instance, the <math>\iiiint\limits_F \, dx\,dy\,dz\,dt</math> formula (triple integral) is converted into an image with the name 49005f50f3ba2dfade3a265ebe363ee9.png. I'd like to know, is this file name unique for each formula ? And is it persisted on the wiki's server indefinitely, just like other images in articles ? To be more clear, is the triple integral formula always going to be associated to this 49005f50f3ba2dfade3a265ebe363ee9.png file ?
I'm trying to implement a cache mechanism in my app that tries to also deal with images generated from math markup (besides usual images in articles), that's why I have this curiosity. I'd like to know if I can safely associate a math markup string with a file name so that there's no need to retrieve the image from the server again when I encounter that formula.

There's no direct way to do this, although I guess it could be
implemented. A workaround would be to do something like
http://en.wikipedia.org/w/api.php?action=parse&text=<math>\gamma=\frac{1}{\sqrt{1-v^2}}</math>&format=yamlfm
, which will give you the HTML generated for this <math> tag, which
could be an image (like in this case), or HTML if the formula is
sufficiently simple (try a^2+b^2=c^2 for instance).
