Yep, pretty much this. I'm planning on using this for a gallery-style character list article and I feel that the default eight images is too constraining, even with the Show More link.

An option to control how many rows are shown would be nice.

EDIT: And another thing, can old and new galleries be implemented at the same time? I feel that both gallery styles have their own niches to fill, and I don't like the load times when opening images to a new window.
