No thumnails showing

Hi,

When I want to show a gallery on my frontpage there is a large white space generated. Actually the space for the thumbnails, but they are not showing. When I look in the image folder the thumbs are generated. When I call the gallery with the list option, it works fine.

Any ideas, thank you.

This is how i call the gallery:

{gallery}frontpage{/gallery}

This is the website:
