Hi,
a new parser for internal links [[...]] and ''quotes'' has been committed to cvs HEAD.
Using the new parser, image thumbnail captions can have links via [[Image:bla.jpg|thumb|A big [[bla]] I've photographed]].
The code has broken prefixed links that are used by ar: (Al[[razi]] kind of links). I'll have to fix this tomorow.
A test page is available at http://jeluf.mormo.org/testwiki/wiki.phtml?title=London
