Hi Elliott,
I appreciate your reply. We do have the navigation arrows displaying within a gallery display.

The difficulty we’re having is that the navigation that appears within a portfolio is not in step with the images that are within the portfolio gallery or gallery categories, but instead are related by upload order, it seems.

We need to have the navigation restricted to a gallery, a gallery category, or a gallery subcategory.

Is there a way to specify this range automatically? It wouldn’t be useful to have to do this manually (as we’ve been forced to do with the Post Types Order plugin).

Any further suggestions?

Thanks in advance!
