I'm sorry to say I laughed out loud after reading your comment, but I actually wondered about the same thing while reading the article. :)

You have to admit it would be hilarious if they didn't know the size of the database or wouldn't be able to calculate it easily.

The author of the article does not work at Google. So the article is basically speculation. He has NO CLUE how Google stores the image data.

Surely he could just email the Google engineers and they'll tell him.
