Hi Patrick Julicher,
Thank you for using our services.
Most probably there are some java script conflicts on this page and the the jQuery or Lightbox libraries are not properly loaded. Could you please provide us with a live link so that we can try to see what is causing the improper loading of the java script?
Thank you very much for your cooperation in advance.
