That estimate is actually a bit high due to the client-side caching of images. 
We have a number (just under 100) of domains with their own access logs. 
Taking the most popular domain in May, www.ekno.lonelyplanet.com, we have 
around 200k visits resulting in around 12 million hits. That accounts for 
about half the traffic we see (and one of the apaches I mentioned - all other 
domains go through the second apache).
