So that applies, by design, to both html and javascript?  Does the image 
even get
downloaded, or is it completely ignored?

I've got javascript that's doing something along the likes of the following

function xyz() {
         var x = new Image();
         x.src = 
"http://perfserver:2000/sendmsg.cgi?param1=value1&param2=value2;
}

This function is then called in the onload() and onunload() functions to 
communicate
back to a server (other than the web server) data regarding the performance 
of rendering
the page.  This is a handy bit of functionality, since the setting of the 
src property causes
the page to be fetched to the browser cache which, in this case, is sending 
encoded data
to a server asynchronously.  Since the Image variable is never displayed, 
you don't have
to worry about hiding it in the page somewhere, and you don't really care 
what comes back
from the URL (since it is intended to transmit data).

If you are using HTMLUnit to do performance testing as well as 
functionality testing, then
handling images is important, both the download and render phase, since 
they contribute
significantly to the overall "load" time of a web page.  Or do you not see 
HTMLUnit being
used for performance testing at all?
