I have just successfully installed Drutex on a shared server. As it turned out, for whatever reason my host does not support dvipng, but they do support ImageMagick. However, the convert binary does not accept a dvi input, and so a third program is required to run after latex and before convert. Luckily the binary dvips is included with the texlive package my host installed, making this not a very big hurdle. After creating the custom commands for Drutex the latex finally rendered correctly. This information should be included in the DruTeX documentation as nowhere does it mention that ImageMagick will not accept the dvi output from latex and the user is essentially left wondering why the software doesn't work.
