I think I may have found a way to make the images cache (it works for me at least).

It's a two step process for me to get this working, one with a local JS file and the other with the XML data returned from the server.

1) In the JS file, I simply cache the image like your normally would in JS:

webFXTreeConfig.rootIcon = "images/folder.gif";
webFXTreeConfig.openRootIcon =

image1 = new Image();
image1.src =
image1 =
new Image();
image1.src =

2) On the server side, (I'm using Java in this case), I set the "expires" header for the XML results (I set it to an old date to automatically expire the results):

response.setHeader("Expires", "Mon, 01 Jan 2001 00:00:00 GMT");  // Java example

I'm not certain if expiring the page (setting an old date) is or if simply using the "Expires" header at all is fixing it.

Hope this helps!

This is a known IE bug that has been around since IE4. Preloading images does not help. Im actually not sure there is any workaround.

Using Mozilla you won't have this problem.
