When you decide to make a photobadge on Facebook it will allow you to automatically share your latest photos with the world from one image generated by Facebook. As you might have noticed it doesn’t take all the photos from all of your albums. The reason for this is probably because you have to enable the album for ‘Everyone’, and so the album cannot be set for 'Friends only’ or something similiar. You can change your album-settings by clicking on an album and then at the bottom you will find a link 'Change album settings’.
