So many of my Facebook / Flickr friends ask me this question, I’m going to blog the answer for the good of whoever wants to know. It’s easy, actually; Flickr will link to your Facebook account and automatically post your latest uploads to your FB profile.
Just go to your Flick Account Settings and click on the Sharing & Extending tab. See at the bottom of the page? Where you see “Share Flickr photos to other sites,” click “edit” to the right of “Facebook.” If you haven’t connected Flickr to Facebook, click the Connect button. Check “Automatically share your public Flickr uploads anywhere your Facebook updates are shown.” After editing, Facebook should show “Activity Updates: ON.” Link your accounts to share your Flickr updates on Facebook.” When you upload new photos to Flickr, they will automatically be posted to your Facebook profile.
So, there you have it. That’s how to link your Flickr account to your Facebook account and have your Flickr photos show up in your Facebook profile.
