Hey all!  
I was just wondering if anyone could help me out… I’m wondering how to modify

```auto
 target_mc.onRollOver = function() { 
this._alpha = 40;
thumbNailScroller();
};

```

so that instead of just becoming alpha = 40 on the mouseover, the movieclip transitions through animation. anyone know? I’m following the tutorial here…  
[http://www.kirupa.com/developer/mx2004/thumbnails.htm](http://www.kirupa.com/developer/mx2004/thumbnails.htm)

Also,  
Right now, I’ve got a whole bunch of thumbnails being loaded into an array that are sloppy in size… can someone give me an idea how I’d set a mask for these images? thanks!
