Here is a quick way to change the permissions on all your Flickr photos:
- Open the Flickr Organizr.
- At the bottom, click Select all to choose all your photos. All the photos in the photostrip at the bottom will be marked in red outline now.
- Drag any of the bottom photos to the work area in the middle. All the photos will be added to this area now.
- At the top, click Permissions and choose Who can see, comment, tag? In the dialog that pops up, choose the permission you want applied on the photos.
