With the number of photos I have and the wet piece of string linking me to the internet, I think I would have noticed if it were uploading all my pics, added to which I have a monthly traffic quota which I would have breached.

When I saw the title I thought it was referring to the T&C of Picasa's web albums, which says they can use your photos for purposes such as marketing and publicity. That's why I don't use the web albums feature any more.
