Guest Passes let you share your photos that aren't public.
Anyone can see your public photos anytime, whether they're a Flickr member or not. But! If you want to share photos marked as friends, family or private, use a Guest Pass.
If you're sharing photos from a set, you can create a Guest Pass that includes any of your photos marked as friends, family, or private. If you're sharing your entire photostream, you can create a Guest Pass that includes photos marked as friends or family (but not your private photos).
1. Take a picture of yourself right now.
2. Don’t change your clothes, don’t fix your hair…just take a picture.
3. Post that picture with NO editing.
4. Post these instructions with your picture.
