There is, however due to some bugs in IE5 and Ie5.5 - it is not always
reliable - see MSDN - Q269802.

function preload(imgObj,imgSrc) {
if (document.images) {
eval(imgObj+' = new Image()')
eval(imgObj+'.src = "'+imgSrc+'"')
}
}
function changeImage(layer,imgName,imgObj) {
if (document.images) {
if (document.layers && layer!=null)
eval('document.'+layer+'.document.images["'+imgName+'"].src =
'+imgObj+'.src')
else document.images[imgName].src = eval(imgObj+".src")
}
}
eg then
<script language="JavaScript">
preload('submit0','images/submit0.gif');
preload('submit1','images/submit1.gif');
</script>
Then you still have to use the object in your references to actually display
it.

Subject: [DUG-OFFTOPIC]: OT: re-using web images
Hiya, a bit off topic, in a webapp I'm writing I end up having about 100
references to an img file (small bullet point), which seems to take ages to
load up (the webserver sits there for ages pumping out these bullet
images), does anyone know if theres any funky java script thing I can do to
preload the image once into the browser, then simply reuse it and save on
the download time?
