Sharing a Flickr photo or video has become that much easier, with a new Share this! button that provides tools to email, embed, link to, or blog any Flickr photo or video. Although sharing options aren't entirely new (you could always "Blog this", for example), the email option is the snazziest new feature. It auto-completes your Flickr contacts or accepts any full email address. If you're not crazy about just anyone emailing your photos with this tool, head to your account page to change who can use the Share this feature on your account. If you're like me and you got excited about the idea that you could sideload pics from another Flickr account to your own using your Flickr upload email address, it unfortunately doesn't seem to work.
