Topic: change thumbnail size for multiple galleries

i am really confused.  i understand how to make multiple galleries in a Flash movie and i understand how to change the thumbnail size in the options.as document.  i do not understand how to change the thumbnail size for multiple galleries.  when i change the options.as it only changes the thumbs in the simpleviewer.fla file and not the multiple_galleries.fla file under Flash embed.  i hope that made sense.  thankx.
