// I have noticed a problem (race?) in Netscape 4 where sometimes
// document.images is null at time this code is executed. One
// solution is to delay the cacheing until the document is loaded
// by placing this in an onLoad function. This has ugly ramifications
// for use of this logo in general web pages. For now we leave it as
// is and see of the problem crops up in real use.
//
// The test for document.images is to prevent failures in older browsers
// where images are not available as JS objects.
