after some test it runs with the default entry's in the generated htaccess file really good ...
But i have found one problem, i have the free version from "JSN ImageShow FREE" also for some testings installed and there is some problem with that.

the error of this module itself is "Gallery Module can not be loaded". my first thought pointed me to new activated .htaccess file but there are to many options, the most of them i do not really understand :)
maybe someone can help me a bit?
