Preload many images

I have tried several preload scripts found here; plus, some of my own.
The only thing that works is the unsophisticated loading of those
tiny images. The download consist of 100+ images amounting to 50+mb;
and, normally completes in less than 1 minute without preload (using
DSL). The preload terminates after 6 or 7
images and seems to time-out in the middle of an image. A reload will
download a few more, etc. I have used the <body onLoad=function()>
approach as well as the
non-function approach of JS that executes immediately with the page's
loading.
Getting the same results with Netscape-7 and IE-6.

I need to add: The source of the array containing the image
references is a '.js' file. That doesn't seem pertinent as some of the
images always load.

Got any ideas??

OK. This is a very simple one. For NS4.7 it preloads anywhere from 2
to all (79). For NS7x it preloaded 7 and on restores it downloaded a
few more each time. For IE6 it consistently preloads just the last
image (#79).

<script src='imageFile.js'></script> // contains the array 'pics'
<script language='javascript'><!--
/*-------------Function to preload images----------------*/

function doPreload()
{

for(loop = 0; loop < pics.length; loop++)
{
var an_image = new Image();
an_image.src = pics[loop];
}
}
/*-------------------------------------------------------------------*/
//-->
</script>
</head>
<body onLoad=doPreload() bgcolor="#004f00" text="#ffffff"
link="#ffffff" vlink="ffffff" alink="ffff48">
