You might want to try "Nikon Image Space" (
www.nikonimagespace.com ).
I just started using it so have to learn of the details on organizing/sharing methods.
There are 2 free hosting plans available. a basic one for anyone to use with 2gb space available and a second plan for registered owners of Nikon equipment providing 20gb of storage space
Upload, organizing, sharing look to be pretty easy. From what I gather this service is a work in progress but pretty well done, as you would expect from a major camera company.
Here is a link to a sample pic that I just posted for public sharing of a A&F Filli Rizzini. I noticed that using this simplistic method gives me an encoded URL that does not display here but can be linked to.
From what I can tell I should be able to get a true .jpg link once I do a more formal organizing.
Nikon Image Space A&F Flli Rizzini I'll try to figure out how to get it to embed/display here later. I do know that it is possible to create and share selected albums.
oh yes, no spam that I can see.
