I only had one bug. The module "languaje selector" doesn't read the joomfish css. So it is always -raw images-.(for me no problem, it fits with my web style).
Thanks a lot to the developers! And also thanks for the video tutorial in your website, useful!!!
I only have one problem: after publising the plugin, it was written an error in the upper part of the content area (but the plugin worked good!). I solved this by including the following code in line 15 in file jwts.php
(cheers and sorry for my bad english)
