Well, it's common to preload images using JavaScript for rollover
buttons and such, but I'm not sure if that could be used to change the
priority of image loading. You can give it a shot, though. Here's code
that would otherwise be used to do it:

function preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.p) d.p=new Array();
var i,j=d.p.length,a=preloadImages.arguments; for(i=0; i<a.length;
i++)
if (a.indexOf("#")!=0){ d.p[j]=new Image; d.p[j++].src=a;}}
}

You'd pass as many urls to images to that as needed. This is a
function that Macromedia Dreamweaver 2004 would throw in the head and
then it would be called in the OnLoad handler of the body element. You
can try to call it some other way to get it run sooner, though.

Hi Victor,

Also, mostly such image or other page stuff loading is mostly depend on the
client webbrowser.
