// Google+ was already a great #social network for photographers but this new feature in the most recent #googleplusupdate  is simply awesome. You can now: 

– use your mouse wheel to zoom in or out
– click and drag to pan right, left, up or down

Try it out!
Note that this is 2000×1300 pixels screenshot of the interface. If you want to see the full image, head over to the announcement post by +Dave Cohen http://bit.ly/RFkNa5

(Let's see how many years it will take Facebook to copy this :))
