hide link "next" at last slide, "previous" at first slide....

hi,

for a manual slide show, am trying to hide "next" link when it reaches last slide...

$(document).ready(function() {
    $('#slideshow').before('<div id="nav">').cycle({
        fx:     'scrollHorz',
        timeout: 0,
        next:   '#next',
        prev:   '#prev',
        pager:  '#nav',
        end: function() {  // both following lines are ignored...
            console.log('end');
            $('a#next').css('visibility', 'hidden');   
        }
    });
});

and how would I hide "previous" link when at first slide?

thank you...
