Hi Smitherinez,
While we’ve never specifically tested the plugin with groups, it pulls photos based on your Facebook ID (or in this case, maybe your Groups ID) – you can find the ID between the 3rd and 4th slashes within the URL of your Facebook Photos page.
http://www.facebook.com/YourFacebookID/photo_stream
If you take your Facebook ID and put it within this URL:
http://graph.facebook.com/YourFacebookID/albums
Then visit the URL with your browser you should be able to see a page of text (JSON) data, so if you don’t see an error message within the first few lines, then the plugin should be able to retrieve the albums and photos successfully.
Hope that helps.
Cheers.
We should also mention that if you do see an error message on the URL regarding Authentication, then that is most likely caused by your Photo Albums being publicly inaccessible, and not an issue retrieving photos from Facebook Groups.
Marking as resolved. Cheers.
