THE MOST RECENT UPDATE:
Maintenance
Facebook made changes to their app code on May 1st, 2015, and as a result of those changes, the connection between Fine Art America and Facebook is temporarily disabled. We've modified our code to work with their changes, and we're now just waiting for the tech team at Facebook to review and approve our code. The review process should be finished by May 11th. At that time, you can come back to this page, re-enable our Facebook app, and everything will start working correctly again.
In the mean time, you'll just have to do things old-school. After you upload a new image to Fine Art America, just copy and past the URL into your Facebook timeline.
