jQuery - Photo gallery

Would somebody be so kind and tell me, why this script only works in Firefox and not in Chrome. Script: when it is finished it should be a simple Photo gallery Thank you for your help!!!

$(document).ready(function() {
            function animate()
            $( ".picture" ).delay( 2000 ).fadeTo( "slow" , 0.00, function() {
                    $( ".picture2" ).animate({ opacity: 1.00 }, "slow" );
                    $( ".picture2" ).delay( 2000 ).fadeTo( "slow" , 0.00, function() {
                        $( ".picture" ).animate({ opacity: 1.00 }, "slow" );
                        animate();
