I doubt it has anything to do with congestion, but there's certainly
something odd happening. I'd wager it has nothing to do with Tor
either so it's probably off topic. But here's my input anyway. Maybe
it will lead to a quick resolve. ;)

I see the exact same thing Brian sees using Tor/Privoxy with Opera 9.01
or Firefox 1.5.0.4, but Konqueror 3.4.2 displays the thumbnails just
fine. That's a Fedora box with yesterday's Tor Alpha-CVS and Privoxy
3.0.3.

My first guess was referrer logging, but I puttered with that setting
in Firefox and Opera with no consequence. It wouldn't explain why it
works naked but not with Tor, but differs across browsers. 

There's some differences in the HTTP headers among the three browsers.
Perhaps someone will spot something Privoxy would "adjust" in one case,
but not the others?? Here's what I see, including some of the actual
HTML because it's apparently relevant but I don't immediately see
what's triggering the differences...
