I’ve used Aeon Nox for years and I normally add a line to the variables.xml so that if a show doesn’t have a Season poster, it will default to the TV Show poster.
<value condition=”Container.Content(seasons) + IsEmpty(ListItem.Art(season.poster))”>$INFO[ListItem.Art(tvshow.poster)]</value>
Is there a possibility of this being added as a default, I’m sure others may find it useful as the black/white icon looks a little ugly.
