I would like the guest to see perhaps 1 picture in each set of photos but nothing more.

For such a simple need, change the "who can see these photos?" property to "admins, family, friends, contacts" (but not "everybody").

If you want to apply to all your photos:

1) go to Administration>Photos>Caddie
2) if the caddie is not currently empty, in the "Caddie management" check the "Empty caddie" option and click on the "Submit" button
3) go back to the gallery (click on the "Visit the gallery" link in administration header)
4) with a theme like "Sylvia" or "clear" you have a button to "display all elements in all categories and sub-categories", click on this button
5) click on the "add to caddie" icon (all your photos are in the caddie)
6) go to Administration>Photos>Caddie
8) change the "who can see these photos?" property
9) select "all" as "target"
10) click on the "Submit" button

Then if you want disconnected visitors to see a few photos in each album, just change the "who can see this photo?" property to "everybody" for a given photo.

To make all photos visible to people you know, set their "privacy level" to "contact" in the Administration>Users>Manage screen.
