"A must have"
This is a no-brainer. Stamp sets the foundation for managing large sets of images. I shoot around 20,000 pictures a year and couldn't live without it. At first you might not "get" the way it names files but it'll make sense pretty quickly. Somewhere on their site you can find a good whitepaper on how to organize your images. (Did I mention it's never crashed or messed with an image?)
