Fanart without downloading Movies etc.

Hi Guys,I love Xbmc and Aeon,but I can;t seem to find the answer,Please delete if in the wrong place.
I like watching 48 Hours,from Cbs News.
First click on CBS News,then select 48 Hours
But there is No fanart or posters,just blank Dvds
Is there a way to get fanart the same way when selecting my Movies?

Thank you very much
Gerry
