Photos which are uploaded are not displayed on activity unless a user is logged in. This has not always been the case. I have checked that settings and as far as i can see settings are Public, I can't find anywhere where this could have caused this issue. I have 2 users other than myself who have uploaded photos. When I look in CB/plugin/gallery/media I can see that the only difference is that the album for one user is empty as per the attachment and these images appear, as does an image before which is in uploads album
