Update April 3rd: As per this LL blog post, the Facebook photo upload has been re-enabled by Facebook.
Update April 2nd: The lab have now officially announced this project viewer – see my blog post here. I’ve also included the filters wiki page link below, now it is publicly accessible
On Tuesday April 1st, Linden Lab introduced the SL Share 2 project viewer, version 3.7.5.288424, which incorporates support for both Flickr and Twitter.
These options are designed to work alongside the existing SL Share to Facebook feature, and provide the means to link your SL account with your Twitter and / or Flickr accounts and then send tweets (and photos) or upload photos.
The new options have their own dedicated toolbar buttons (Flickr and Twitter) and can also be accessed through the Communicate menu.

The two floaters are similar, in that they include a tab for connecting to your Flickr or Twitter accounts, and a tab for uploading messages / snapshots.
The account connection options will open floaters allowing you to log-in to Flickr or Twitter and authorise the linking of your SL account to them. Once linked, the Twitter floater allows you to send Tweets either with or without snapshots attached. Both of the floaters allow you to include your current in-world location as a part of a Tweet / with a snapshot.

Insofar as snapshots are concerned, both capabilities provide the following options:
- A refresh button
- An image size drop-down
- A filter options drop-down (users and developers can design their own filtering scripts if they so wish using the filter documentation in the wiki
- A preview button for checking how shots will look prior to upload.
Additionally, the Flickr floater includes the ability to provide snaps with a title, description, and Flickr tags.

Finally, the SL Share to Facebook floater has also been updated with this viewer:
- The photo floater includes the same filter options, etc., as the Twitter and Flickr options, although there is no longer an option to include a SLurl, as per Facebook’s requirements (see right)
- There is a new Friends tab, which I assume lists all your Facebook friends when you SL account is linked to your Facebook account. I have no idea if any additional functionality is available in the tab, as I don’t use Facebook and so cannot check.
At the time of writing, it is unclear whether or not the Facebook photo upload block has been lifted by Facebook or not. As I reported in my week 13 SL projects updates, LL believe they have updated both the viewer and the back-end intermediate process linking to Facebook in order to comply with Facebook’s requirements. However, any official lifting of the block by Facebook as yet to be confirmed by the Lab.
Currently, the new SL Share 2 features are only available in the project viewer, and will not be available in the release viewer until they progress to a release status.
In the meantime, details on the new project viewer can be obtained from the release notes page, which includes download links to the Windows, Mac and Linux versions (as does the viewer’s entry in the Alternate Viewers wiki page).
