Great extension, though this extension just add s0 to the address to get the full size image anyways
It tracks ALL urls with Google Analytics! This way the author could view all photos! Also it uses jQuery to retrieve a single object from the HTML which is really a waste of 92,6kB...
[UPDATE] And a day later it's fixed! Awesome. [/UPDATE] I love this extension, but it's having some trouble with the new G+. Many images are not opening at full size. Hope it's fixed soon!
