Changing the header text to an image

Hi, With template #6 can some one please tell me how I can change the header text <text_header> in the custom.xml file to an image. Instead of it scrolling the text across, I would like it to scroll the title as a jpg.
Any help would be appreciated, thank you!

Hi,
Sorry but you can't replace text by an image on this kind of banners

Hi, thanks for your last responds. I have another question, is it possible to outline the text with another color, or put a shadow effect on the text in the custom.xml file
thanks again
