Preloading Images for Slide SHow

[jakester]

I have this slide show for various stuff we sell. We have these 8 jpegs, so in order to save bandwith, I created an array of Image objects so the jpegs get cached and the browser won't keep downloading the pictures. The code works faultlessly but it still shows in the IE status bar each time the jpeg changes that the same jpegs are being downloaded from the server instead of using the cache.
