[Theme: WP-Creativix] How to cope with the Header Image slider if an article has no image?

Hi all!

How to cope with the Header Image slider if an article has no image?
-> if an article has no image, the image slider will show an empty box?
-> so how to remove this empty box and show only the beginning text of that article?

Thanks for any kind of help!
