Google has added many new features in a free update to its Picasa digital photo service. Among the enhancements are the ability to e-mail pictures via the Gmail service and faster posting to Blogger. The update also has some new editing features, like a "fill light" tool to brighten dark, backlit photos. Users will also be able to export photos to printing services such as Shutterfly, Kodak's Ofoto, Snapfish and Walmart.com.
