Xml photoalbum help (MX2004)

I am using the tutorials on this page where you can make a photoalbum using xml. I had to change the code alittle so that i could use buttons instead of previous or next buttons. My question now is that when i go and change the pictures in the xml file they wont change to what they should be. Is there any way to get them to change after i change them in the xml file?

My fla file along with the xml file are in the attachment

Thanks for your help
