show Plugin/addon-Fanart as shortcut property

helllo

how can i ad the fanart from a addon which i set as a shortcut (script skinshortcuts) as a property?

did already try it via "button 404" and was able to create a property within the shortcut includes, but wasnt able to catch the fanart.
Did try stuff Like:

<onclick>SetProperty(customValue,$INFO[Container(211).ListItem.Art(fanart)])</onclick>

<onclick>SendClick(404)</onclick>         

So, how do i have to do this? how to get the Fanart from the Addon/Plugin which i set as a shortcut?


EDIT:  if thers a easyer way than to work with a Propetry, suggestions welcome. But as it seems, i cant just use ListItem.Art(fanart) within the List, as the script seems to store only certain stuff like path and so on.
