Hi Imre,
Here is the link after we added a new vivid color building image for the home page section like the demo. The instructions did not say to put this image in the Feature image of the Home page, but we just did. We also put it in the appearance section under header background image too.
You can see from the link, that the image is now in, but too dark. We have set all colors for header to transparent.

Yes thank you on the info on the footer nav. That is not fixed with dummy content and okay.
So we still need help making the header image more visible.
