웹에서 Tex를 사용하는 것에 대해 drupal.org 에 괜찮은 문서가 하나 있네요.
참고로 이글루스는 mimetex를 쓰고 있다고 합니다.

  • jsMath is a piece of javascript that renders the TeX on the client's browser. This means that you do not have to install any TeX rendering software on your server and the processing of TeX does not increase the load on your server. The downside of course is that the user's browser has to work harder and the display of the mathematics takes a bit longer. With the default setting jsMath will display the page to the browser initially with all the TeX syntax still in place and will then start converting this into typeset mathematics. So the user can already start reading the page while jsMath is still converting the TeX. You can get an impression of how well this works by looking at examples. If you do not want to shift the work of processing the TeX to your user's browser then you should go with one of the next two modules.
  • Mathematics Filter uses MimeTeX to convert the TeX to images that are then included in the webpage. This requires you to install the mimeTeX executables on your server. MimeTeX does not use the standard TeX engine but renders directly to images. This makes it very fast. It does however mean that, like jsMath, it can render only a subset of the complete TeX syntax. For most applications this will not be a problem. But if it is the you should go with the DruTeX module instead.
  • DruTeX uses the full LaTeX engine to convert the TeX to dvi and then uses ImageMagic and dvipng to convert the dvi to images. This means that unlike the other solutions DruTeX can handle the entire TeX syntax. The drawback however is that you need to install several software packages on your server before DruTeX will work. Also the processing of the TeX will put extra load on your server. DruTeX is quite an impressive module with its own plugin architecture. It has its own discussion group.
  • TeXfilter is similar to DruTeX in that it requires a LaTeX installation on your server and therefore brings similar advantages and disadvantages. It is a simpler module than DruTeX but
