I successfully created a post showing photos using your gallery: http://bba-n12.ch/wordpress/?p=120
but when looking at the posts overview: http://bba-n12.ch/wordpress/?cat=5
I don't see a preview of the gallery as with the default gallery. But there is only blank space. When looking at the page source I can see that the plugin is loaded, but does not display anything.
Is there any way I can get a gallery preview on the posts overview?
