* Function		: LPF_MouseOver(imgName, imgOther, imgPath, imgControl)
* Description		: Display another image when mouse over
*						  When user only wants to change one image when mouseover (most mouse over effect is this case), set imgControl to 1
*						  When uesr needs to change two images to the same image when mouseover, set imgControl to 2
*						  If user wants to change the image only when it's currently displaying a specific image, use imgControl = "e"
*						  If user wants to change the image only when it's currently not displaying a specific image, use imgControl = "ne"
*						    (eg see www.hsbc.com.hk/hk/personal/bank/waystobank.htm. There are 3 states for the buttons,
*						     on, off and over. Normally it will show the off state. When user moves mouse over it, it will
*						     change to over state. It will return to off when mouse out. When the user clicks the button,
*						     it will change to on state. When the button is at on state, there will be no image change whether
*						     the user mouseover or mouseout the button)
* Parameter Usage	: imgName		: The name of image
*                   imgPath		: Path of the image for display when mouse over
*                   imgOther		: This usage depends on the value of imgControl
*                   imgControl	: If this is 1, then only change the src of the image with name = imgName to imgPath
*													imgOther will have no use in this case.
*											  If this is 2, imgOther should another image name.
*													Both the imgName and imgOther will change to imgPath
*											  If this is "e", imgOther should be an image src.
*													If imgName's src = imgOther, then change imgName's src to imgPath. Otherwise no change.
*											  If this is "ne", imgOther should be an image src.
*													If imgName's src != imgOther, then change imgName's src to imgPath. Otherwise no change.
*											  Other values will be treated as case 1
