Some idea ?.

It looks like teximg uses some less standard LaTeX packages. (see line 100 of Ikiwiki/Plugin/ in the Ikiwiki source.) A quick work-around for an end-user would be to install the 'mhchem' LaTeX package (look in CTAN ). A medium-term workaround would be to replace 'scrartcl' on line 100 with 'article', and delete line 101 in the teximg source. Longer term it would be nice to give teximg a configurable preamble. Hrm - maybe that configurable preamble should be a todo? -- Will

Yes it works. Thanks. I am writing some code for examples.
