Image Gallery Level Problem?

Hey Guys

I am using a sequential preloader to load these 2 swf files.

The preloading works ok however I cant figure out how to change the levels of the movie clips so they overlap each other when selected.

For example…select image01 and it displays, select image02 and it displays however select image01 again and it does not appear.

How can I make this work >>>>>Image Gallery Flash Files<<<<<
