You can edit your photos with Creative Kit before you share them. After uploading a new photo to a post or album, follow these simple steps:
1. Click Edit photos at the bottom of the share box.
2. Roll over your photo thumbnail to bring up the toolstrip.
3. Click the Edit icon (the pencil) to launch Creative Kit.
