The main problem I see with that is that the <object> tag doesn't have
the same accessibility attributes, so you'd effectively lock out a lot
of people using browsers that don't understand the context of the tag in
this case. I think the better way is to add something to the <img> tag
as you'd still have full backwards compatibility.
