I switched from stoppedesign to stopdesign because of the IE7 flaw. But now I don't have any archived galleries. Just the first 6.

Is there a setting somewhere I'm missing?

As I poke around through the forum I see a similar question at http://www.zenphoto.org/support/topic.php?id=780&replies=3#post-4310.

If I left this setting at 6, or 12, is there no "page" functionality in the theme to get to the rest of the galleries? Do I just need to set this at something higher than the number of galleries I have?

Yeah. In your zp-config.php file, set [b]$conf['albums_per_page'][/b] equal to a high number like 1000 or so.
