Details
(Probably wrong component, can't see a more appropriate)
When Mozilla suppresses the image to just an alt after a 404 on the image,
changing this.src and this.alt has no effect - this technique is often used as
a "is this server up" technique or others.
e.g.
<img src="http://127.0.0.1/i.gif" alt="server up" onerror="this.src='d.gif'"
alt="server down">
The event fires okay, but because the image object has been swallowed to just
text, you can't then change it with src/alt. No script errors are produced.
Jim,
