customizing loading page

According to this documentation http://unity3d.com/support/documentation/Manual/Customizing%20the%20Unity%20Web%20Player%20loading%20screen.html you can replace the Unity logo with your own image by specifying the logoimage value.

I have done this but all it does is remove the Unity logo but doesn’t show my own image. Is anyone successfully using a custom logoimage value? Am I doing something wrong that isn’t documented in the above link?

Oh, and I am using the Pro version.

Are you placing your icon in the correct directory and making sure that the html code references it properly?

We have code that looks like this in our html file (we named our logo spash-image.png):

if ( typeof unityObject != "undefined" ) {

    var params = {
        disableContextMenu: true,
        logoimage: "splash-image.png",
        backgroundcolor: "000000"
    };

    unityObject.embedUnity(
        "unityPlayer", 
        "myGame.unity3d", 
        "100%", 
        "100%", 
        params
    );
}

I realized that I missed the part in the instructions about the image files MUST BE PNG format. Seems odd, but ok.
