Asim Rafiqui, for the Pulitzer Center
On the Getty Images archive you can type in 'Gaza Destroyed' and retrieve over 5,500 images to select from. If you run the query 'Gaza Funerals' you will get back over 7,000 images. I was unable to check the Corbis archives because at the time of writing this entry their site was undergoing maintenance. But I am confident that I would find a similarly large number of images for both the queries above.
