Howto: Get nicely rendered LaTeX images online I decided to use "mathtex":http://www.forkosh.dreamhost.com/source_mathtex.html. It's a nice program indeed, but it needed some tuning for my needs: # By default, LaTeX does not play nice with non-english letters. I fixed that by throwing in a pile of \usepackages. # I hate black-on-white scheme, so I made a modification to source code to allow changing color of rendered formulas on compilation. You can see the results here: [http://dump.bitcheese.net/xet/mtex.cgi?yourformulahere]. Change mtex to mtexi for inverted output. "Modified Mathtex source":http://dump.bitcheese.net/files/nasukux/mathtexi.c.gz ("Patch":http://dump.bitcheese.net/files/mewazol/color.diff) "Makefile":http://dump.bitcheese.net/files/walevaz/Makefile used to build two versions of mathtex used on site You can use "this":http://www.codecogs.com/components/equationeditor/equationeditor.php online LaTeX equation editor (on in "russian":http://ru.numberempire.com/texequationeditor/equationeditor.php), or this fast and lightweight "previewer":http://bomfunk.bitcheese.net/latex.php without any AJAX or JavaScript.
