Need help with XML / Flash

Hey everyone.
I’m hoping someone can help me.
I took a look at a tutorial (which i can’t find) that was similar to the thumb image navigation scheme that you see at Flash Level and I’m trying to create something similar but i’m stuck. I need a larger image of the thumb to display in a movie clip in a flash page.

The XML code i have is :
<images>
<image>
<path>thumb/thumb1.jpg</path>
<WHAT GOES HERE IN ORDER FOR A LARGER VERSION OF THE THUMB IMAGE TO LOAD INTO A MOVIE CLIP IN FLASH?>
</image>

Thanks a ton!
