I tried a bunch of times, but gave up after an hour of playing with it, as not really working on that site yet.  :) 

I did, however, just load the graphic by navigating the URL and save it...seems it's not the scaled back one, but one that is 32x26...32x32 is acceptable I thought? So I should be fine?

Here's the car icon.

edit: I tried it in FireFox and it still displays the DNN ico, though that was removed and replaced with the one linked above (Nothing in IE)...sounding like a cache issue as you mentioned, John.  But I swear I cleared the cache in the host settings and restarted the application ad nauseum a month ago (and then again now to make sure I don't look more stupid).  :)

It did that for me, too, so I right-clicked and hit show picture...and it was there.  Perhaps that's my problem?  :)

I think the problem is that this one is a jpeg rather than bitmap my other sites use.  ;)
