Google Earth
Google Map - is not updated every few months, because the pictures of my house in New Orleans were probably taken in late January, 2007 and they haven't changed in the more than two years since people complained that Google had put pre-Katrina images back up on Google Map, so Google complied at put post-Katrina images back up. I can tell when the pictures of my house were taken because the south side of the maple tree in the back-yard is in bloom or in seed, and I was in New Orleans living in that house December 20 something, 2006 - January 24, 2007.
Microsoft Virtual Earth or Digital Globe had September, 2008 images of part of the the greater New Orleans area up in a free online image atlas.
