LaTeX for Joomla! creates valid HTML of .tex files. There won't be any need for installed TeX environment on the server.
LaTeX for Joomla! is implemented as a content plugin which only needs one or more filenames in an article. Each file will be read and converted to HTML on the fly. Even the use of images or tabular is/will be possible.
Please note: the current release is still in development. But if are interested in using this plugin, please help me finding bugs, missing functions and give me suggestions on how to improve it. You may contact me to get infos about using this plugin - documentation is not available yet.
