How to Make All Private Photos on Flickr Publicby C. Taylor
Flickr offers individual privacy controls over images as you upload them, but you can change those settings any time you wish. If you need to make a large number of private photos publicly available, using Flickr's Batch Organize feature is your best bet. This utility enables you to quickly locate all private photos and then change the permissions of all those photos with one selection.
Log in to your Flickr account, point to "You" and select "Organize."
Click "More Options" to expand the search capabilities.
Click the "No Privacy/SafeSearch Filter" drop-down menu and select "Only Show Private Content."
Click "Select All" and drag the selected photos to the main Batch Organize pane.
Click "Permissions" and select "Who Can See, Comment, Tag?"
Select "Anyone (Public)" and click "Change Permissions." Click "Thanks" to close the confirmation dialog.
