If you’re a small business with a Facebook page, there may be times when you want to tag your own personal friends or contacts in a photo. It could be from an event, a project, or something more informal. In any case – if you click on the photo and go to tag it, the only taggable options that appear are other Facebook pages – not personal accounts.
It’s easy to get around this on the desktop site. Just right click on the photo and open it in a new tab or window. When you click ‘Tag photo’ you’ll now be able to tag your friends.
