Mira, asi lo estoy usando y funciona, por ejemplo esta pagina se llama "preload.htm" (lo que en realidad sería el index.htm, pero yo la llamo desde una animación flash):
Código HTML:
<html>
<head>
<title>NombreSitio.com * Preload Image Page</title>

// You may modify the following:
var locationAfterPreload = "index1.php" // URL of the page after preload finishes
var lengthOfPreloadBar = 350 // Length of preload bar (in pixels)
var heightOfPreloadBar = 16 // Height of preload bar (in pixels)
// Put the URLs of images that you want to preload below (as many as you want)
var yourImages = new Array(
"imgs/top/img11.jpg",
"imgs/top/img12.jpg",
"imgs/top/img13.jpg",
"imgs/top/img14.jpg",
"imgs/top/imgXX.jpg")
// Do not modify anything beyond this point!
if (document.images) {
var dots = new Array()
dots[0] = new Image(1,1)
dots[0].src = "imgs/barra.blanca.gif" // default preloadbar color (note: You can substitute it with your image, but it has to be 1x1 size)
dots[1] = new Image(1,1)
dots[1].src = "imgs/barra.verde.degrade.gif" // color of bar as preloading progresses (same note as above)
var preImages = new Array(),coverage = Math.floor(lengthOfPreloadBar/yourImages.length),currCount = 0
var loaded = new Array(),i,covered,timerID
var leftOverWidth = lengthOfPreloadBar%coverage
}
function loadImages() {
for (i = 0; i < yourImages.length; i++) {
preImages[i] = new Image()
preImages[i].src = yourImages[i]
