The Golfskin is programmed with the Google Earth network-link feature. Every time you load the Golfskin you will see the most recent content. Make sure you don't load the Golfskin multiple times.

You can also manually refresh each network-link by right mouse clicking on it and selecting the Refresh option. The network link image should turn yellow and animate from side to side. When it turns green and stops moving the content is then refreshed.
