function Load_Page (strURL) {
	// Check if the referring page is htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp.  
	// htm_images.asp, htm_images_2005.asp and htm_images_win2004.asp are special pages because they don't use a frame to hold the flash nav - instead the flash nav is embedded 
	// into the file itself (i.e. htm_images.asp) which has no frames of its own.  Normally, the flash nav is held in the 'nav' frame (on the left), 
	// and content pages are displayed in the 'content' frame (on the right).  Normally when a user selects a link from the flash
	// nav, the content frame reloads with the destination page, and the nav frame reloads the corresponding 'background image' 
	// behind the flash nav, so that it matches the destination pages' background image.
	
	// When the user is on any page other than htm_images.asp, htm_images_2005.asp, or htm_images_win2004.asp, and they click the 'images' link on the flash nav, the following 
	// events occur:
	// 1. The 'nav' frame holding the flash nav is resized - pushed off the left of the screen so that it is invisible, and the 
	//    content frame takes up the entire screen.
	// 2. htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp is loaded into the content frame.  (as mentioned above, htm_images.asp has it's own embedded copy 
	//    of the flash nav and htm_images.asp, htm_images_2005.asp and htm_images_win2004.asp does not use any frames of its own.)
	// 3. So now there is the previous pages' flash nav in the 'nav' frame, which is hidden off the left of the screen, and the 
	//    'content' frame contains htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp which contains its own embedded flash nav.

	// PROBLEM: 
	// If the user now clicks any link on the flash nav in htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp, it will resize the frameset, bringing the 'nav' 
	// frame (which holds the previous pages flash nav background image) back into view, and the 'content' frame which 
	// contained htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp will be reloaded with the destination page (whatever link they clicked on. eg. htm_lookbook.asp) 
	// This is a problem because the flash nav needs to reload a 'background image' that corresponds to the page being viewed 
	// in the content frame (as mentioned earlier).  
	// Normally the one flash nav file is used in all pages, and sits in the 'nav' frame, and onclick of a flash nav link, 
	// the flash nav background reloads to match the destination pages' background. However, the flash nav embedded in 
	// htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp has no way of telling the flash nav in the hidden 'nav' frame (which will become visible when the 
	// destination page loads in content frame) what link the user clicked, and therefore what background image to load 
	// when the destination page is loaded.
	
	// So, we need to have code that checks if the referring page is htm_images.asp, htm_images_2005.asp or htm_images_win2004.asp, and if so, load the correct flash nav 
	// background (that corresponds to the destination page being loaded into the 'content' frame) into the 'nav' frame.
