Ahhhhh.....I see what's happening here. Let me help to remove some confusion:
1. The right side of every page holds widgets, which are just a display mechanism for pictures, whether or not those pictures are in sets. If you remove a widget, it does NOT remove the pictures from your site, it just removes that particular display of your pictures. So, if you remove the "Get Acquainted" widget, your pictures will still appear in the set on the Sets page, and the individual pictures will appear on the All Photos page.
2. I think you've made more changes since my last post last night, but at that time you had 218 pictures, which are organized in 11 sets right now. If you delete a set, it doesn't delete the pictures in it, it just deletes that particular organization of the pictures.
3. Each widget is limited to 50 pictures, but you can have as many widgets as you want. There isn't a way, though, to combine a limited number of sets in a single widget, though: you can choose "Any or None", or you can choose a specific set, but having 3 specific sets in one widget isn't an option.
So...all that said, I think you should try removing the "Get Acquainted" widget on the right side, and add a new widget for "Al Smith". If you want me to do that, I'm happy to do that for you, but wanted to make sure that's what you want.
Did I help at all?
