Load swf file on click of (javascript)navigation label

I am trying to make a (heavy)swf file slideshow. for that i have created navigation labels at the bottom of the html page using javascript.And my my 'aim' is when i 'll click on any navigation label,particular swf file will be loaded. Here i'm getting problem is , when i open that html file all swf files are loaded at the same time. so when i click on nxt label part of swf only displays.

so what is the soln to this?

is there any way that when i'll click on navigation label 开发者_C百科only that time particular swf file will played and when i'll go to nxt label, previous label shoud have to unload.

I think that instead of pre-loading, you should load the SWF files dynamically, changing the src attribute of the element in the moment it is displayed.
