Ok, we've created the first version of a new FCK Plugin that we've called equation_html, which can be found in ~/plugins/equation_html/fckplugin.js

This tries to insert pure html directly into the text, i.e.

<img src="http://latex.codecogs.com/gif.latex?..." alt="...">

To use this you'll need to modify fckconfig.js, so you have:

FCKConfig.Plugins.Add( 'equation_html', 'en' ) ;

removing

FCKConfig.Plugins.Add( 'equation', 'en' ) ;
FCKConfig.Plugins.Add( 'tagprocessors' ) ;

There are a couple of negative to this plugin over the original:

• currently can not double click on an existing equation to edit it.
• you can not use LaTeX notation, i.e. \[ .. \] or ... to create equations without using the editor.

If there is enough interest in this new plugin, then we'll make the above modifications.
