When I make the setting
Admin Options > Do you want Members Gallery to show all of a users photos? to - No
...then the Recent / Random group of thumbnails show up as per each category index.
When the above setting is set to yes, they only show up on the main page index.
Whew, what a relief!, because we have Most Recent at the top of the page and I was getting double vision seeing them twice.
I had set it to No because this is the only way you can see what pics have been loaded specifically into `members gallery'.
Now that I have moved these pics into their respective galleries, I have set it back to Yes.
