Hi John
The next question for you.
I'use RS Gallery [SVN570] and Joomfish (1.8.2). In my site I've a french and a german version.
laperroterie dot fr
left side Menu option    Nos photos
When I choice with the Joomfish selector german, the first time the RS Gallery URL are ok language=de,
when I choice the sub gallery the RS Gallery URL go back to the default french URL.
With Joomla content it's work, with RS Gallery no..
I've try it with the Joomla URL, and also with the new plug-in RS Gallery for SH404SEF

http://extensions.siliana.net/Forum/sh404SEF-plugins/4358-RSgallery-2-plugin.html

I think that the developer of this plug-in is now also in this forum, I prefere to stay with the SH404SEF Plugin, perhaps some other Joomfish user can make some test with the standard Joomla URL.

A+
Michael
