Xinha configuration: how to change language and image upload path

Issue Summary

I changed already to FCKEditor, but it's so slow and crappy that I want to change back. Reason to change was that I didn't find any way to change editor language and image upload pluging's file path.

Xinha doesn't seems to understand Drupals language like FCK does, how should it be configured? (Language I use is finnish and it is found in Xinha's language folder).

Is it possible to use IMCE with Htmlarea/Xinha? Or is it possible to change Xinha's own upload plugin's file path to some user related path?
