I'm having a lot of trouble with this. In the database on the zenpage theme(a modified zenpage is the theme I am using), I have the Albums per page set to 20 and the albums_per_row set to 4. It should create 5 rows of 4 then when listing sub-albums under the main album but it does this:

http://www.goodfreephotos.com/places/

I can't get it to obey the 20 variable. What is going on?

I am sorry, I fear I don't understand. What I see is an album "places" with 20 sub albums. These are listed with 5 rows with 4 albums each. Which seems to be what you wanted?
