After accessing Image.complete, Image.onload does not fire.
JavaScript code that works under IE-9 and Chrome-16, but not under Firefox-9.0.1:
var slides = []; slides[0] = new Image(); slides[0].src = fileNames[0];
var tmp = slides[0].complete;
slides[0].onerror = function(){
alert("While downloading\n"+
" " +fileNames[0]+
"\nerror occurred. Execution stops");
throw new Error("Network problem");
};
alert("X " + tmp);
alert("Y ");
slides[0].onload = function(){
alert(this.complete);
if (winStarted) winStart()
else window.onload = winStart;
};
The alerts "X" and "Y" give output, but the onload branch is not taken. Onload branch is taken under IE-9 and Chrome 16.0.912.63.

Could you create a working testcase on http://jsfiddle.net/ (save and post the link here), please.

This fiddle alerts: FF-9 "Complete branch; Chrome-16 "Complete branch" + "Onload branch" ; IE-9 "Onload branch".
There seems to be an onload for XUL images, but I can not find it for html images.

Maybe you can use element.addEventListener instead. Something like:
s.myonload = function ....
s.addEventListener("load",s.myonload,false);
s.src = ...
