I know how to display image in the center of screen, but I think Facebook uses other way.
before I click an image, the address is "https://www.facebook.com/chen.jay".
but when I click an image, the address becomes "https://www.facebook.com/photo.php?fbid=206288359454&set=a.433212919454.230419.804139454&type=1&theater".

after I close the image, the address change back to "https://www.facebook.com/chen.jay".

I believe it doesn't reload the page so I wonder how to do it.


Thanks.
