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.
