I've always loved this photo taken during The Blitz of WW2. To me it shows the general stiff upper lip outlook that Britain has. "Oh our house may have been bombed, our lives may be in tatters, but lo and behold we still have time for a cup of tea!"
This Ap is awesome. If your camera is ever lost/stolen, you can download a photo you have taken (with the embedded serial number) and it will search for matching serial numbers posted on the internet, so you can see if anyone is using your camera and posting images from it!
