That pretty much hits the nail on the head.  If we're going to pretend that 
this is in the XHTML family, then a line break is definitely different from 
having two paragraphs.

Using <br/><br/> is bad style anyway.  Why didn't you just end the paragraph 
at that point?  Is it really semantically the same paragraph even if the 
reader is about to see a blank line before the other half of it?

I agree with this.

In addition to this, the following rather trite response could apply: "We're 
using CSS everywhere else... aren't there width and height properties in CSS 

At least that's what the W3C seemed to think... the width and height 
properties are going away _entirely_ in XHTML2 (along with the <img/> tag 
itself... but we can ignore this, since we seem to prefer <img/> to the more 
useful <object/> here.)

And as for "Clients may decide to avoid downloading very large images", what a 
load of rubbish.  Anyone can say width="1" height="1" on the tag for a 1MB 
image file... it doesn't make the file any smaller at all. ;-)
