In general I think your point is valid. Just remember that it probably
also matters how you count page views. Because technically images are a
separate page (and this thread did discuss serving up images). So if
there are 20 graphics on a specific page, that is 20 server hits just
for that one page.
I could easily see an image heavy site getting 100 hits / page. Which
starts meaning that if 1M users hit 10 pages, then you get 1M*10*100 = 1G.
I still think 100G views on a single website is a lot, but 100M is
certainly possible.
