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='javas cript'><!--
/*-------------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=doPreloa d() bgcolor="#004f0 0" text="#ffffff"
link="#ffffff" vlink="ffffff" alink="ffff48">

hi everybody let me say right from the start .. I´m not a coder ... "just" a designer! that said .. here is my question: I´m using dreamweaver´s built in preloader for a menu. it looks like this: function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length;

I usually use some "pre-load" code in my pages to preload graphics that will be swapped. But, I'm thinking that rather than the long, repetitive, once, for each graphic hardcoded stuff like this: var bb_off = new Image(); bb_off.src = "images/bb_off.jpg"; ....that I could have an array where I just listed the names of the graphics, a loop, and code in the loop that cycles through each entry in the array to create and pre-load the "on"...

Has anyone else had this issue? Basically, the preload of images for a rollover effect for the navigation is really really slow when using IE 6.0 but when i view the site using Netscape, it's fast like it should be(no lag!) My problem is that since 96% of users use IE, i need to figure a way to fix this. Below is the javascript currently being used. The arguments are passed in before the script is called.

Hi, I'm hoping for a bit of advise-- I have a (relatively, from the point-of-view of this dilettante) complex script that attempts to preload certain images in order to trigger one of a series of six slideshows (rather than try to articulate, have a look here): http://www.slack.net/~stacey/stestbed/homejs.jsp Clicking any of the six blocks of text along the sides will begin a loop of the corresponding slideshow.

The following is a script that I have written that preloads images for an image gallery. The problem is that the images only preload in Safari, other browsers load each image when it is called. Any ideas? imgSeries = new Array(); curImg = ''; function loadkill() { document.getElementById('loadingtxt').style.display = "none"; document.getElementById('imgone').src = imgSeries; document.getElementById('imgtwo').src = imgSeries; }
