Topic: hide gallery in flash

Is it possible to hide the complete gallery in flash?

Take a look (the button "Bilder"):

It doesn't seam to be possible to hide the gallery by pushing an another button. I don't have the gallery in an extra swf-file and I would like to prefer to let it like it is. I just need a function or something to hide and to show again the gallery (not delete). It is important not to load all the pictures again.

Does somebody have an idea?
