What will your custom field's value be?  The name of a field in the posts table, or something else?  If the former, I assume there's a finite set of options which you would test against (otherwise you might end up having a SQL injection vulnerability?)

What about it do you want to be simpler?   AFAICT NextGen doesn't give you hooks into their queries so you'll have to do it with SQL.

Anyway, here's a standalone file you can put in your root and I think it should give you want you want, minus the display order I haven't implemented yet.  Let me know if this is what you are looking for?
