Changing Who Can Blog Your Flickr Photos
One of the things I really like about Flickr is the slick in blog integrating they've created. With only two clicks, I can go from seeing a photo I liked on Flickr to publishing it as a new blog post.
However, not every Flickr member wants their photos blogged by strangers, which is a perfectly acceptible feeling. Flickr offers a couple options for this crowd:
1. Set your pictures to private, friends, family, or contacts. Private photos are just that. People won't blog what they can't see. Friends, family, and contacts settings will limit blogging to people you know.
2. Adjust who can blog your photos. This is done here:

Adjust this to your own custom comfort level.
I believe the default setting is "Any Flickr member" so if you haven't changed this setting, expect it to be wide open.
