I use theme_display_cat_list to hide my categorys of protected albums.
It works great all categorys without pictures are hided.
My problem is i have got a hirarchy for famaly like:
Headcategory
Subcategory 1
Album 1
Album 2
Subcategory 2
Album 1
Album 2
and so on
So the headcategory has no album itself
Is it possible to modify theme_display_cat_list to show empty categories when there are subcategories
