How to show an image while waiting for the game to finish loading

Hi, I am developing a game for unity web player that has only one level.

I was wondering if it is possible to create two levels where the first would be just an image to show while loading the second level (the "actual" game).

The idea is to skip the web player loading screen as fast as possible by loading a very small image and then show that image while loading the rest of the game.

How can I do this without Unity Pro?
