Where to find free NextGen Gallery templates?

Does anyone know of a source for free NextGen Gallery templates? I didn’t find any from a Google search so I’m wondering if some other WP users here may have found some.

One of my searches did produce a thread here in WP support where someone mentioned a site (https://nextgen-gallery.com/templates/) with several templates but for the life of me I don’t see how to get them. If there is a “download” link on that page I must be blind because I don’t see it.

I started to wonder if those templates were already included with NextGen but I tried adding some of the template code and none of them worked.

Thanks in advance for any help you can provide!
