2 questions with css for old browsers

[jmc92]

1 Is there a script for preloading images even if browser cache is turned off
2 I have an image map and when I hover over each link I would like a different image rollover to show a small image button

And I need it to work on ns4

Thanks in advance for anyone with a solution

I'm no longer up on NS4, but as to your first question, no. By definition preloading can only be accomplished when the browser's cache is enabled AND when its cache is large enough to hold all of the images being preloaded plus whatever else it wants to cache for the page(s) that are open in it.
