If you’re one of those group-happy sorts of Flickr people, you’ll be pleased to know that the new Organizr now gives you the ability to add photos to your groups. Look for the “Your Groups” tab at the top, and then drag and drop to your heart’s content. Or, use the “send to group” button you’ll now find when you have a batch of photos in the “Batch Organize” tab. (In the not so distant future we’ll be giving you the ability for you to open up a group in the Organizr to remove photos from the pool, but we wanted to get the ball rolling with this limited feature set ASAP.)
