Picasa storage cost

Q: What is the cost of extra GB, ie when we use lots of video clips?
A: The blog is free; but any photos or videos that you upload to your blog will automatically create a Picasa web album on the internet. The first 1Gb for Picasa is free. You can buy more Gb if needed:http://picasa.google.com/support/bin/answer.py?hl=en&answer=39567
