Google is making it a little simpler to share your Picasa Web Albums photos to whichever destination you want, with the launch of easy share buttons for Google Buzz, Blogger and Twitter. To share a photo or album from Picasa Web Albums straight to any of these sites, just click the appropriate icon to the right of your photo, customize your message, and post it. “
We also know that sometimes you don't want to share quite so publicly, but actually just want to share a link to a single unlisted photo, without revealing the whole album. We've now made this possible, by updating the "Link to this photo" URL so that the album name is hidden on the viewer's photo page (the "Share" button still works as normal),” explains Google.
