@til @manton is there a way that the photos page can be pointed to a subset of photos … or can I use a category to do that?

if not - can the addition that @cleverdevil delivered be used to do the same thing?

Why?

We have two things that do essentially the same thing - but they both by default deliver ALL the images.

I want to present on a grid a subset of those images.

Happy to do that with categories - which do now - just not in a grid :-(
