I assume you're talking about references on two different servers,
otherwise the browser can just compare the full URL of both images
and see that they're pointing to the same resource.

But I do not understand why you would have to use an ID. A far better
solution would be a checksum. This would especially help with popular
"stolen" or widely used images, even if they're on different servers.

The now-expired HTML 3.0 draft proposed the MD attribute, which can
be used for exactly this purpose.

Beats me. You'd think that a company who says

  "Netscape remains committed to supporting HTML 3.0. [...]
  We believe that Netscape Navigator 2.0 supports more of the 
  HTML 3.0 specifications than any other commercial client." [0]

would be able to implement the almost trivial MD attribute on
anchors and inline images.
