	This functionality has a few requirements:
	1. Add the <script src="[this file]"></script> 
	2. Call the 'callOnLoad' function from body onload event of the page.
	3. <span id="logo" style="position:absolute;top:-300px;z-index:100"></span>
	4. Works for IE only for NS call createtext function from the body onload event
