thats not a local variable; you are assigning index "i", of the inherited scope/routine scope/public scope array "preload" to reference a new Image object, which is automatically var'd and scoped by that assignment (infact, you'll find that Image isn't accessible by any scope; its scope sort of disapears, and it can only be accessed through the array)

If you were doing this:
Help with Code Tags 
for (var i = 0; i < array_name.length; i++) {
    var thisImage = new Image();
    thisImage.src = array_name[i];
    preload[i] = thisImage;
}

then you'd need (or should use) the var.

If it only works in Internet Explorer; it doesn't work.
