Tabblo, a Photo site upgraded their service with the additon of “wiki ethos with a design tool based on general rules of good layout”. A tabblo is a collection of photo (that you import from places like Filckr, iPhotos, Picasa etc.) and words brought together by a stylized template that can be customized to your heart's content. A tabblo lives at a permanent URL and can be private, accessed by whoever you invite, or public for the whole world to see.
You can share your tabblos, publish them to other sites or blogs, or just keep them to yourself. Once you've designed a tabblo, the only limit in how you use it is your imagination.
