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.
In HTML5 there's no way to get an event when an <img> begins loading. It
begins loading when the src="" is set.
Nothing prevents an implementation from firing ProgressEvents while
loading images though, that would give you an event when an image starts
loading.
I don't think any browser does that as of yet though.
