Desperate to try & sort this... Hope some once can help!

I've searched all over various Flash forums and just can't seem to find the answer.

I have a small desktop app (.exe) done in Flash that uses setInterval to refresh the application.

What I'm now trying to do is now have some rotating banner ads. I would like to be able to change the name of the image (presumably in a xml file) and it update the banners.

Some banners maybe located on different servers so solving this by importing the images into Flash isn't an option. I need to reference the urls of the jpg's somehow through the XML file and have them load into the application somehow.

My scripting skills are limited so I'd really appreciate some code and where it goes within the movie.

Hope someone can help

Many Thanks
