Eric: Problem mit lightbox + Slideshow

Hallo!
Ich habe folgendes Problem. Ich habe auf meiner Website eine Javascript-Slideshow mit einem Script mit dem Namen "lightbox" kombiniert. Dieses bewirkt, dass sich bei click auf einem Bild das einzelne Bild mit einem Fade-Effekt in der Mitte der Seite öffnet.
Jedoch hab ich das Problem, dass die in meinem Slideshow-Skript nicht funktioniert. Außerhalb der Slideshow funktioniert dieses lightbox-Skript jedoch. Inwiefern stören sich die beiden Skripte?
Am besten füge ich mal den Quelltext der Seite hinzu, auch wenn dieser sehr lang ist (Die Url ist: www.bauer-dienheim.de/laura/freunde.html):
