Missing Pictures

After exporting my site pictures in my Hero bloc are missing when I open the site in my browsers (Safari, Chrome and Firefox) The pictures are exported in the imagemap. This is how my site it now with the pictures. I updated my site with a new page and now they are missing. I did not upload the updated version to my server. The Pictures that are missing are in my indexpage and intro page.

On all sites the header pictures are gone when preview or export :roll_eyes:
