Yes, I know. I wrote : "Thumbnails will be selected from the whole lib without set allowed galleries in the script itself." For me its now not a problem. Its just a litte note for people who like to use this.
Maybe an idea for upcomming versions: the select from database should be include the username and his rights inside the gallerie. So only thumbs will displayed that allowed for this user/ guest without set the allowed galleries in the script.
I don't need this right now. the script works fine for me.
