Say cheese!

Believe it or not there are now over 3 billion photos on Flickr.

3 billion!

I of course have only posted 250 because that's all you're allowed unless you pay a yearly fee.

Surely there must be a way for Flickr to offset the annual charge with advertising or some other sort of revenue stream?

I also reckon there'd probably be close to 5 billion pics on Flickr by now if Facebook hadn't come along.
