There are RSS feeds for friends' Posts, Notes, and Statuses, but there doesn't appear to be one available for Photos/Albums. Does Facebook provide one, or is there another way to get an RSS feed for this?
There is no publicly available RSS feed. Tweetdeck uses the Graph API to gather all photos from the user and updates the client based on new one received which aren't already in their database.
There IS a nice solution for Facebook Groups implemented using Yahoo Pipes (which seems to be old and no longer works). Possibly it can be modified to work with users. http://pipes.yahoo.com/pipes/pipe.info?_id=055b7fbcb01605dbd34e5287b8eee8cd
There is Photo2RSS but its reported that it doesn't work always (haven't tried it though).
