This is covered in the FAQ. —Jeffrey

It looks to be possible; I hadn’t considered it, but I’ll take a look. —Jeffrey

Without commenting on the merits of the method itself, I’ll note that you can isolate the preset file by right clicking on the name, and selecting “View in Finder” (or “… in Explorer”). —Jeffrey

The hack involved manually specify the photo album in your export preset.

First, you will need to authenticate to Facebook and create a preset. You can randomly select a folder that you would want to upload to make things more ‘visible’.

Navigate to your photo albums. You should be able to get a URL together with your Facebook ID.
https://www.facebook.com/media/albums/?id=xxxxxxxxxxxxxxxx

Note down the ID. It will come in handy.

Navigate to your Wall Photos album. Examine the link.
https://www.facebook.com/media/set/?set=a.16045060xxxxxxx.31339.10000067xxxxxxx

Your album ID should be the first part after “set=a.”

Navigate to your preset folder, and open your preset with a text editor.

Look for the line ["info.regex.lightroom.export.facebook2_ALBUM_LIST_SELECTIONS"]

There should be some random numbers below the line. Replace the numbers with the numbers that you got from the link earlier. In my case. 16045060xxxxxxx

So

["16045060xxxxxxx"] = true,

Save the text. Launch Lightroom and you should be able to upload to said folders now.

This comment suggests that the plugin is allowed to upload to Wall Photos if only it were to try. The plugin believes Facebook when it says “here are the albums the user has control over, and of those, which one may be uploaded to”, so if “Wall Photos” doesn’t appear in that list even though you actually can upload, it sounds like a FB bug. Personally, I don’t even have a “Wall Photos” album in my FB account so I can’t test any of this… —Jeffrey

This may not be news to you, but a possible key to the mystery about why the Facebook wall doesn’t show up in the list of albums for upload with your plugin is as follows:

If, within Facebook, I go into Albums, most of the albums have a little gear icon with a pull-down menu. Mousing over the icon brings up a tooltip that describes the visibility of that album (e.g., “Your friends of friends”).

However, the Mobile Uploads and Wall Photos albums are different: There is no pull-down menu for these albums – they’re apparently special. However, there is a gear icon, and mousing over the gear brings up a tooltip stating “You can change the audience for each photo in this album”.

Now, the odd data point. I uploaded an image from my Lightroom collection to my Facebook Wall Photos earlier this evening. After I uploaded it, I decided to rebuild the list of Facebook folders – and lo and behold, the “Wall Photos” item in the list disappeared. I realize that this is known behavior that you mention in a FAQ on the Facebook plugin.

This is pure conjecture on my part, but, given that I was just able to upload an image to the “Wall Photos” album, I wonder if the problem with that album being absent is simply because it’s special-cased by Facebook and that if I could only see it again, I might have permission to upload to it.

Naturally, it’s a shame that any of us have to dance around due to Facebook’s inconsistencies, flakiness, and tendency to break things willy-nilly. But it is what it is, I guess. I hope the data point mentioned above is of some use.
