Nivo slider sliding problem

Im having problems with nivo slider. Everytime i add a slide it adds as an image and not as a slide below of the previous one. Here is my site http://www.glare .cl
i have no idea what’s the problem since it stopped working with no apparent modification.
i can’t leave my site like this and really need help from an expert. The support forum from my template is nowhere to be seen and i’m really desperate please help :c
