The module is called "mod_gk_news_image_3" in position "header" and the component behind it is called Gavick Photoslide GK2.
We want two more parameters in the backend for each image:
URL: the location the image links to
Target: Choose between _blank or _parent
The small images in the bottom of the module on the front page should not be changed. It should be as now, i.e. when you press a thumbnail picture, the slideshow goes to that image.
