491288 Make flash banner cache images

I have a flash as2 banner that loads external images via xml in a loop. But when the loop restarts the banner doesn't take images from the cache but loads again and again from the server. here's a banner: [login to view URL] xml nodes: slide1: - title slide2: - subtitle - desciption - image url - link url you can either let me know how easily fix this or recreat the banner. looking forward to your bids.
