Check out your photos at lightroom.adobe.com
In addition to Lightroom mobile, we’ve also launched Lightroom web, a new way to view and share your images from any web browser. Available at http://lightroom.adobe.com.
The announcement was probably downplayed because there isn’t much you can do with it now. You can view your photos individually or play a slideshow. The interface is very sparse and its not clear if they’ll be adding more features to this down the road.
