i don't know how to do it.... could somebody bring me this 2 functions in a endless loop please instead of a hover Event.

$(document).ready(function(){

$("img.a").hover(
function() {
$(this).animate({"opacity": "0"}, "slow");
},
function() {
$(this).animate({"opacity": "1"}, "slow");
});



function imageOneFade(){
$('#img1').fadeIn(2000, function(){ setTimeout("$('#img1').fadeOut(2000); imageTwoFade();",6000); });
}

function imageTwoFade(){
$('#img2').fadeIn(2000, function(){ setTimeout("$('#img2').fadeOut(2000); imageOneFade();",6000); });
}

$(document).ready(function(){
imageOneFade();
});

});

many thanks
