Preloading XML

Hi All,

I have thumbnail images loading from and XML file. My problem is I need to control how they load, so they all load at the same time or load in sequence. At the moment they seem to load randomly. My thinking was if I could monitor the thumbs loading I could control them, but I carn’t get their BytesLoaded or BytesTotal.
You can view the loadingHERE
And files if anyone can help [HERE](

What I need is to load the thumbs and fade them in at the same time as happens when the images are cached, like the second time the name is clicked.
