[Volcano Man]

The best way to install an update is to create a new folder on the desktop. Unzip the update to that folder and then go into the folder and look at the files. If you don't want any art related changes to happen in the update, just delete any artwork (.bmp) files you find. Once you are satisfied, back out to the main folder and cut and paste everything into the game's fold on your hard drive. If you did it correctly, it will ask you to overwrite. Say yes and voila, you have installed only what you wanted to install - no need to reinstall anything else.

Obviously that is more advanced than just extracting the update to your game's directory, but it allows you complete control over what you do and do not want overwritten.
