Flash & XML : fast?

Hi,

I want to make a website for my dad as a Christmas present. He is an amature photographer and he wants a website to show off his candy.

The problem is he can’t do a thing with HTML and stuff, so I thought of XML which is better readable, and a Flash app that shows the photo’s. So the only thing he has to do is to just alter the XML file.

If this XML file grows to for example 250 nodes, isn’t this going to take forever to load? Or is XML in combination with Flash fast & reliable?
