I'm trying to make sure some images are preloaded no matter which page on the site a person hits first... without Redirecting to another page. It seems to me this would be done with a Flag. But, I think it would be passed in the Address bar, so if the page gets added to Favorites it will have the Flag info with it- thereby skipping the preload on their return by way of Favorites.
I haven't tried it yet, but so far I've come up with putting this line at the bottom of the preloader page...
Then put this on every page...
<?php $opener="yep"; ?>
Does this look ok?
TIA for your comments and suggestions.
