Uploaded images not shown on website

Hi,

I've reinstalled a campsite instance on a server (running
DirectAdmin).
Everything seems to work fine, only the images aren't shown.
When people
upload the images from the backend, everything seems to work
fine. The
website is located at http://www.nieuwsbedrijf
.nl. Can someone point me
in the right direction to solve this problem?

Regards,

Jeroen
