Is it possible to make a thumbnail the default on a top level category that also contains subcategories? At the moment, I can assign default thumbnails for subcategories, but the top level category thumbnail appears to just take the most recent upload from the subcats.
Because of the way I am setting the gallery up, some top level categories only contain subcategories (ie, no images at the topcat level). So I suppose the question is, can I make a subcat thumbnail the default thumbnail for the top level category? Hope that makes sense!
