Hello. Many thanks for a speedy reply.
The Privacy Settings> Default status for Gallery/Media Is set to Public. There is no Non public, just Public, Private, Logged in users only, Friends only and Group only.
I have a custom built theme, which may not help. I have just done a further upload of images via the little grey box in my test member profile and that image is not even showing in my gallery wall, yet it can be seen in the main library of images in the Admin Dashboard. Hope this makes sense.
