They don't always not appear in the elements collection, but it would be
reasonable to say that it would not be a good idea to expect to be able
to find them there (as they commonly will not be present).

It would be unexpected for them to appear in - document.images - as it
is explicitly a collection of IMG elements, no elements that happen to
be displaying images (such as maybe OBJECT).

It is certainly a unhelpful peculiarity where forms are concerned.

I think you will find that this behaviour originates with a Netscape
browsers. Netscape 4 had no means of referencing these elements (as they
did not even support event handlers), and that may have also been true
for earlier versions (thus pre-dating scriptable IE versions).
