Loading Images Once

[tryangle]

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...

<?php $opener="yep"; ?>

Then put this on every page...

<?php
if(isset($opener)){
include("$PHP_SELF?");
}else{
include("./preloader.php");
include("$PHP_SELF?");
}
?>

Does this look ok?
TIA for your comments and suggestions.

It's not Redirection, because I'm not trying to send people to another website... but it involves sending them to "another page" temporarily- but only if the images haven't been preloaded.

The images are available (as menu rollovers) on every page, except I don't want to preload them on every page. I was wondering if I could pass a variable through the address bar if the images have been loaded, but then if a person returns directly to a page- other than index.php (via Favorites) I think the Flag and everything would get saved along with the address. Then upon return, the images wouldn't be preloaded. How can I workaround that?

Thanks...
