Nivo slider stop function

Greetings,

I am using Nivo slider on the homepage but there is some conflict with my installation but your Nivo works on my test page.

Question is I need the ability to stop the autoplay at the last slide. I am using this in the Nivo js to do it:

slideshowEnd: function(){}, // Triggers after all slides have been shown
        lastSlide: function(){ $('#slider').data('nivoslider').stop(); }, // Triggers when last slide is shown

Is there a way for me to mod the plugin so we can have the same action?

Thanks
