Good lord, I am about to cry...

I am trying to make a simple (or, so I thought) slideshow, which displays up to four images, about 30k each. As far as I can tell, this should be easy using the following method:

var newImg = new Image();
newImg.src = "images/testImg.jpg";

BUT! It would seem that IE has a prolem with this, and downloads the images again each time it is called for display. (I believe Netscape executes the script correctly.) This wouldn't be a problem with a 2 or 3k image, but since these images are 30k+, there is a slight lag time between clicking the "Next Image" button and displaying the image. I have read another way of doing this here, but I can't seem to get a handle on this example.

Can anyone help me? I am going crazy trying to figure this out!

You can generate the code to preload images for free here: http://www.searchbliss.com/webmaster..._generator.htm
This could help along with the code you have.
