Project Thumbnail Grid only showing first two entries

[billyben]

Hello, I am using a Page as a Footer, in wich i use a Project Thumbnail Grid to display further Projects. Somehow only the first two Project Thumbnails appear, all the others appear with a Broken Image Icon (and my Site Name as caption…). When i click on the invisible Thumbnail i do land inside the Project. Any Idea why The Thumbnail Grid is not Working properly?

Here is the URL to my Website:
