I installed the quickstart package, have done some content modification but cannot get the header to display the image there, it uses the Image Show GK 4 module and while I can get it to display text it does not allows to have the image. I was able to get it on the homepage by disabling the "Use Style CSS" from the "Advanced" tab of the Image Show module but obviously loosing all the css styling of the module itself in the process so I reverted to not having the picture shown.
