Found a bit of metadata.

Go to "Layers" and go to the bottom and there's a button for DigitalGlobe. When you punch that, the image footprint is displayed with the date. I can't tell whether that is the acquisition date or posting date. But they're probably with a month or so of each other.

There are a lot of images posted for the Baghdad area. Somebody was even able to pick-out a large explosion.
