Moving to Photoshop forum
Shouldn't this thread be moved to the Bridge or Lightroom forums, thats the only way I know how to create a connection, unless Elements has a way.
As far as manually doing so, photoshop can save jpg or png files which can then be uploaded via a web browser which can be connected to the facebook albums.
I am not sure if customer is looking something specific from Photoshop or meant Photoshop Lightroom in the discussion.
Will wait for the clarification from the OP and will route accordingly.
In Bridge click on Window/export panel.
