thanks for this great Template. I´m trying to change the image of the Artsliders (Home & Blog) but I have no idea where to do it. Can you let me know where I can change the images for the artslider?

I made a new menu item which goes directly to the Blog 3 column layout. In the overview the headimage is shown but clicking on an article there is an empty space i nthe header. In the other article the header is shown? Any idea?
