Decent Sized Pictures

What I've never understood about the print media (or CNN or BBC) on the internet is why they have such tiny ass photos of stuff. Goto CNN, there photos are usually 220x168. The BBC's are even worse at 203x152. The NY Times is sometimes a little better. The Seattle PI's website very rarely has photos.

But then you goto a blogger who talks about Seattle related news and you get 512x384 on the article with links to 2048x1536.

Why doesn't the real news post photos that have detail? What do they lose by keeping the good photos from us?
