Picassa+Description

While not nearly as popular as flickr, the free photo management and sharing service that comes with all Google.com accounts offers the ability to easily create slideshows with captions (a slideshow is generated from a Picassa Album". In addition, each image in the slideshow can be added to a map, and the entire slideshow can also be viewed via Google map interface. Slideshow creators can allow images to be downloaded, to be made into collages or videos (see example of a Collage made from the Dominoe story photos)

Slidesdhows can also be easily shared via twitter, Google Buzz, and posted to a Blogger web site.
