That's really interesting.
What will blogger do if people who didn't read their helpful howto/didn't get it link to AP/REUTERS/Other peoples photos? Is there are a place for the copyright holder to easaily let Blogger know of an infringement?

I find that more often than not one has to jump through a bazillion hoops to report infringers (at places like flickr/blogging tool places etc) and really go out of ones way to prove that one has the copyright of X. Thus if one finds an infringing collection, say lots of Associated Press photos by umpteen different photographers piled high in these places I can't simple point it out to blogger/flickr/whatever that X-place is certainly infringing - because I'm not the copyright holder. Even when it's that obvious. wtf?
