Transition in Slideshow not working

Today I managed to create a slideshow in javascript that has a fancy transparent transition, however, my problem is that after it reproduces the first 2 images, the next ones won't appear, and the slideshow repeats the second picture over and over again.
I've tried a few methods that did not work at all.
Any help and insight to the problem will be very important to me!
Here is a link to my code: eBRabp
My Javascript code:
// JavaScript Document
var myImage = document.getElementById('mySlide');
var imageArray = ["images/slider1.jpg","images/slider2.jpg","images/slider3.jpg","images/slider4.jpg","images/slider5.jpg","images/slider6.jpg","images/slider7.jpg"];
var imageIndex = 0;
function changeImage() {
mySlide.className = 'hiding';
setTimeout(function() {
mySlide.setAttribute('src', 'images/slider2.jpg','images/slider3.jpg','images/slider4.jpg','images/slider5.jpg','images/slider6.jpg','images/slider7.jpg' + imageArray[imageIndex] + '.jpg');
mySlide.className = 'showing';
}, 1000);
imageIndex++;
if (imageIndex == imageArray.length) imageIndex = 0;
}
var intervalHandle = setInterval(changeImage, 3000);

Problem is in: mySlide.setAttribute... line... It will not work, of course, because you have placed too much (wrong) arguments. You need just two, and since you have array of images set, simple, do this:
mySlide.setAttribute('src', imageArray[imageIndex]);
And it should work:

How to evenly time fading transitions?

so I'm trying to create a simple slide show from scratch, and so far I was able to get full screen images to fade out and fade in infinetly, but for some odd reason using setInterval(function(){fade(var)}, 3500);didn't work, maybe someone can explain why the first and last images took way longer than 3,5 seconds to fade. Meanwhile, I was trying to solve that problem by implementing a callback function in the fade(). My example has four images, and they start fading out until it reaches image one, then don't fade out image one and start fading back in image two until image 4, and do this forever, here is my recent attempt to implement a callback function:
var i = 4;
$(document).ready(function(){
fade(i, fade);
});
var fadeIN = false;
function fade(objectID, callbackfn){
var fadeTime = 3500;
if(!fadeIN){
$("#slide-"+objectID).fadeOut(fadeTime);
i--;
if(i === 1) {
fadeIN = true;
}
}
else{
i++;
$("#slide-"+objectID).fadeIn(fadeTime);
if(i === 4){
fadeIN = false;
}
}
if(arguments[1]){
callbackfn(i);
}
}
But that is not working, it fades out image 4, image 3 and stops on image 2. Maybe there is a way to evenly time the fading transitions using the setIntervel(), if so can someone tell me how? Appreciate any help.
Here is a JSFiddle to the code: http://jsfiddle.net/8kgc0chq/ it is not working tho.

Here is the doc for .fadeOut()
There is an optional argument complete:
A function to call once the animation is complete.
Put the next animation in there, they too take a complete (callback) function.
$("#id").fadeOut(fadeTime, function() {
// code to execute after animation complete
});

You need to do it properly with javascript. Easy way fails after last element.
So here is my solution. Can it be improved further, I think yes.. But it does work now. And is future proof to some extent.
I cleaned up css and changed html structure a little.
Demo: http://jsfiddle.net/8kgc0chq/3/
$(document).ready(function () {
$(window).resize(function () {
realTimeHeight();
});
realTimeHeight();
startSlides();
});
function startSlides() {
var fadeTime = 1000,
delay = 1300,
i = 0,
slides = $("#hero-slider > .slide"),
len = slides.length;
slides.hide();
var pF = $('<div class="slide">'), pB = pF.clone();
pF.attr('id', slides.eq(i).attr('id'));
$('#hero-slider').prepend(pF).prepend(pB);
setInterval(fadeThisIn, fadeTime + delay);
function fadeThisIn() {
pB.attr('id', pF.attr('id'));
i = ++i % len;
pF.hide().attr('id', slides.eq(i).attr('id')).fadeIn(fadeTime);
}
}
function realTimeHeight() {
var altura = $(window).height();
$("#hero-slider").css("height", altura);
}

Simple loop for images

I'm trying to build a simple image slider (but using a fade effect). Every two seconds, the image should change to another image. At the end, it should call repeat_sponsor() again, to start over, so it becomes a loop.
I've written this (highly ineffective) code for 5 images. Turns out I'm going to need it for around 50 images. My editor just freezes when I add too much code.
I've tried using while-loops, but I just can't figure it out how to do this the right way.
Anyone who can help me with this?
function repeat_sponsor()
{
$("#sponsor2").hide();
$("#sponsor3").hide();
$("#sponsor4").hide();
$("#sponsor5").fadeOut("slow");
$("#sponsor1").fadeIn("slow", function() {
setTimeout(function(){$("#sponsor2").fadeIn("slow", function() {
setTimeout(function(){$("#sponsor3").fadeIn("slow", function() {
setTimeout(function(){$("#sponsor4").fadeIn("slow", function() {
setTimeout(function(){$("#sponsor5").fadeIn("slow", ...

(function (){
var cnt = 50; //set to the last one...
var max=50;
function show() {
$("#sponsor" + cnt).fadeOut("slow"); //if you want the fadeout to be done before showing next, put the following code in the complete callback
cnt++;
if(cnt>max) {
cnt=1;
}
$("#sponsor" + cnt).fadeIn("slow");
window.setTimeout(show, 2000);
}
show();
})();
But the real issue is the fact you are loading tons of images from the start. You will be better off changing it so you only have a small subset of images and change the source.

You should use some sort of for loop and a class for hiding the images. and add a max value that if checks out resets c & i
var i=0;
var c=1;
function repeat_sponsor()
{
$("#sponsor"+i).fadeOut("slow");
$(".sponsers").hide()
$("#sponsor"+c).fadeIn("slow", function() {
window.setTimeout(repeat_sponsor(), 3000);
}
i++;
c++;
}

Just run a function every two seconds with setInterval and appropriately target your different sponsor divs:
var i = 1;
var max = 50;
setInterval(function() {
// Could target all other sponsor images with a class "sponsor"
$('.sponsor').fadeOut();
// Execute code on the target
$("#sponsor" + i).fadeIn();
if (i === max) {
i = 0;
}
i++;
}, 2000);

Creating Image slider using only jQuery

I'm trying to create an image slider using Jquery.
What I have is a main div with 3 sub divs with images.
Take a look at this fiddle. FIDDLE
Ok now i got the design just the way I want it. What is missing is the functionality.
When i hover over the div or the images, I want it to act like a clockwise slider.
This may look a bit confusing. Take a look at this demo. This is what i want.
DEMO
This is what i want.The right div gets filled with the middle image src , the middle div gets the left div src. The left div get an new src from an array of images i have defined. Currently i can only change one image div at a time.
However I don't want to use any more plugins. Only Jquery plugin. A CSS only solution would be the best but I do not think it will be possible.
JQUERY
$('.maindiv img').mouseover(function () {
var image = this;
loop = setInterval(function () {
if (i < images.length - 1) {
i++;
$(image).attr('src', images[i]);
} else {
i = 0;
$(image).attr('src', images[i]);
}
}, 1500);
EDIT: I managed to get one part of this working. CHECK THIS.Just need to add fade effect Now the problem is after the images in the array end the first images dont loop back... Had not thought of this before.Does Anybody know how i can get over this issue?

Mabye something like this:
jQuery(document).ready(function () {
var images = [];
var loop;
var i = 0;
images[0] = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQ1GfA01TRDgrh-c5xWzrwSuiapiZ6b-yzDoS5JpmeVoB0ZCA87";
images[1] = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQQSyUWiS4UUhdP1Xz81I_sFG6QNAyxN7KLGLI0-RjroNcZ5-HLiw";
images[2] = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcT_E_OgC6RiyFxKtw03NeWyelfRgJ3Ax3SnZZrufNkUe0nX3pjQ";
$('img', '.maindiv').mouseover(function () {
//Get divs inside main div and reverse them, so right is first
var divs = $($('div','.maindiv').get().reverse());
//Set up loop
loop = setInterval(function(){
divs.each(function(key, div){
if (divs[key+1])
{
//All divs gets image src from previous div > img
$('img', div).attr('src', $('img', $(divs[key+1])).attr('src'));
}
else
{
//This is left div
if (images && images[i])
{
//If picture url not in array then add it
if ($.inArray($('img', div).attr('src'), images) == -1)
{
images.push($('img', div).attr('src'));
}
$('img', div).attr('src', images[i]);
i++;
if (i>= images.length) i = 0;
}
}
});
}, 1500);
}).mouseout(function(){
clearInterval(loop);
});
});

How to make an image slider in javascript

I am implementing an image slider in javascript/jquery.
The demo should work like this.
http://londatiga.net/tutorials/scrollable/
Anyway I don't won't to rely on jquery.tools.min.js because this lib is out of date (the last update is about 8 months ago ).
I decide to make the js code by me.
When clicking on next or prev button I would like to shift the images on the list of one item/image.
The script shifts the items but the display is quite crappy, because the next items is not displayed.
The list is made of 4 images. At the beginning only the first two images are displayed, then when clicking on the next button I would like to display the second and the third image.
Actually the script shows just the first and the second image even if I click on the next button.
Here is the demo: http://jsfiddle.net/xRQBS/5/
Here is the code (1)
Any hints how should I fix it?
thanks

/*global jQuery */
(function ($) {
var imgs = [
'https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcSsarNmO4Vdo5QwHfznbyxPmOyiYQ-KmBKUFsgEirvjW6Kbm7tj8w',
'https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRfIAfLXj3oK1lso1_0iQploSKsogfJFey3NnR0nSD9AfpWjU7egA',

'https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRAPO77sVu-Xk80S_txagySoTq8gKHgeiS63a9TYtKbPpGYVI5X'
];
var $list = $('.list-images');
var $slider = $('.slider');
var slideImage = function (direction) {
var unit = 150;
var left = parseInt($slider.attr('left'), 10) || 0;
left = (direction === 'prev') ? left - 150 : left + 150;
$slider.css('left', left + 'px');
};
$(function () {
$.each(imgs, function (i, img) {
$list.append($('<li>').append($('<img>').attr('src', img)));
});
$('body').on('click', '.direction', function () {
slideImage($(this).attr('data-tid'));
});
});
}(jQuery));
​

With the animate function:
$slider.animate({'left': left + 'px'}, 1000);
http://jsfiddle.net/xRQBS/6/

I'm assuming that you want the shift to be more of an animation. If so, take a look at jQuery's animate. Something like this:
$slider.animate({left: left + 'px'});
That will give it a sliding effect, which what I'm assuming you want :)
