The flash banner below is a BannerZest banner, inserted in an iframe. The banner animation is from the Aquafadas website to show that it can be done.
To insert the content on the page you need to upload the banner directory and all its files to somewhere on your webspace. Next create a node, set the input format to full HTML input, and then put something like <iframe name="bzAnimation" src="http://www.yourwesbite.com/files/banner/bzAnimation.html" width="600" height="250" allowTransparency="true" frameborder="0"></iframe>.
View the full node to see the banner in action.
