I'm using Apple's Aperture to manage photos on my laptop. It has a built-in "share to Facebook" feature, which allows me to create a Facebook album and upload photos into it.
The procedure
When I create an album from a set of photos, I can choose "Everyone", "Friends of Friends", or "Only Friends" for the privacy settings. I've been choosing "Friends of Friends".
The photos take several minutes to upload. It's clear that the photos are actually being uploaded somewhere.
The activity indicator correctly shows when I most recently added a photo via Aperture:
(and this timestamp updates if I add another photo to the album from within Aperture).
The problem
When I view my list of photo albums, I only see this:

and when I open the album:

Is there something I need to do to make Facebook recognize the photos that have been uploaded? (Is this a problem with Facebook, or is it an Aperture problem and I should be looking for solutions elsewhere?)
(Note: I've successfully used Aperture's Facebook integration before — and I don't believe anything about my configuration has changed since then.)
