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,
