The 133527964 part of the URL is the Flickr picture ID.
However, the full Flickr picture URL is http://flickr.com/username/picture-id, so so the picture ID is not enough if you don't know the username.
Luckily, googling for the picture ID on the flickr site is likely to point you to the right direction.
http://www.google.com/search?q=site%3Aflickr.com+133527964
In this case, it returns two links, and one of them is the picture you're looking for:
http://flickr.com/photos/carradine65/133527964/
Enjoy
