Animation playing in loop ???

Here's a screen grab: After you press Ctrl+Enter go to the View option and choose the bandwith preview (see the print screen). Look at the graph: Your banner is divided into frames. See the first line is the longest one and it reaches nearly 2kb (the menu obscures it). It means the first frame is almost 2kb, the rest are less, which means the longest time for the visitor to wait is for the first frame to load, after that frame is loaded the rest are "peanuts"

I've downloaded your file, seems fine to me.
