Nivo Slider set transition to fade

I recently updated my web site and added the Nivo Slider. It works great but I was having some trouble finding out where to set the transitions to ‘fade’ only. To do this you have to update the jquery.nivo..slider.pack.js file. At around line 67 find this

nivoSlider.defaults={effect:’random’,slices:15,

change ‘random’ to ‘fade’
