True, I missed it. The script shouldn't work anyway because you can't append
fallback content elements to <embed>. HTML 5 doesn't allow that either, if I
read well.

Jquery, Ext.js and others all add methods to the Array prototype, but I'd be
surprised if they added elements to arrays. If using jQuery one cannot loop
through array elements using 'for in' then that's really scary! Maybe you mean
objects, as class instances, where you get all (almost) the enumerable
properties...

I just tried 8 <object> tags with SVGs (+ scripts and SMIL) and IE8 runs all of
them fine for like 5 secs and then crashes. With no plugin it loads the fallback
png's fast.
