This service is provided by Nikon, who has a vested interest in providing a good customer experience for its customers of cameras.

They offer 2 gigabytes of free photo hosting space including the ability to upload and preview RAW files from the web.  If you need more photo hosting space, they charge $3 per month for the next 200 gigabytes.

Its not the best deal in the world, but when you are looking for freebies, every little bit can be useful.  You might not save enough money to buy a Harley or even used Harleys for that matter, but you might just save enough to buy some gloves or a tank of gas.
