1. Which readystate does an img object have, before it is added to the
var i = document.createElement("IMG");
alert(i.readystate); // afaict the state SHOULD be uninitialized here...
i.src = "some_url.jpg";
The example applies to iframes as well, i believe.
2. How can we listen to the onreadystatechange, if we want to trigger
an event when the object starts loading? It will not change readystate
since it was already in the state loading.

The state should not be "loading" when the object is in fact, not
loading nor in any of the other states...
