HTML and JavaScript Image Slideshow only links to the same hyperlink rather than different ones for each image

Question

I am creating an image slideshow in HTML and I want each image to link to a different webpage and each image to show a different title/alt tag. However the code I am using is only giving me one link and one title rather than different ones.

I have tried to ways of doing it now but neither seem to work. I will post the first way now and the second way in a different message so we don't get confused.

In the html file the code is as following:

div id="slideShowImages">
    <a href = "civil_war.html"><img src="Images/civil_war.jpg" alt = "Captain America: Civil War" title = "Captain America: Civil War"/></a>
    <a href = "agents_of_shield.html"><img src = "Images/agents_of_shield.jpg" alt = "Agents of Shield" title="Agents of Shield"/> </a>
    <a href = "fantastic_four.html"><img src = "Images/fantastic_four.jpg" alt ="The Fantastic Four" title = "The Fantastic Four"/></a>
    <a href = "jurassic_world.html"><img src = "Images/jurassic_world.jpg" alt = "Jurassic World" title = "Jurassic World"/></a>
    <a href = "Furious_7.html"><img src="Images/paul_walker.jpg" alt = "Paul Walker in Furious 7" title = "Paul Walker in Furious 7"/></a>
</div>
<script src="slideShow.js"></script>

The code in the slideShow.js are as follows:

    window.addEventListener('load', slideShow, false);

    function slideShow() {



    var globals = {
    slideDelay: 6000, // The time interval between consecutive slides.
    fadeDelay: 35, // The time interval between individual opacity changes. This  should always be much smaller than slideDelay.  
    wrapperID: "slideShowImages", // The ID of the <div> element that contains all of the <img> elements to be shown as a slide show.
    buttonID: "slideShowButton", // The ID of the <button> element that toggles the slide show on and off.
    buttonStartText: "Start Slides", // Text used in the slide show toggle button.
    buttonStopText: "Stop Slides", // Text used in the slide show toggle button.    
    wrapperObject: null, // Will contain a reference to the <div> element that contains all of the <img> elements to be shown as a slide show.
    buttonObject: null, // If present, will contain a reference to the <button> element that toggles the slide show on and off. The initial assumption is that there is no such button element (hence the false value).
    slideImages: [], // Will contain all of the slide image objects.
    slideShowID: null, // A setInterval() ID value used to stop the slide show.
    slideShowRunning: true, // Used to record when the slide show is running and when it's not. The slide show is always initially running.    
    slideIndex: 0 // The index of the current slide image.
  }

  /* MAIN *************************************************************************************************/

  initializeGlobals();  

  if ( insufficientSlideShowMarkup() ) {
    return; // Insufficient slide show markup - exit now.

  } // transitionSlides

} // slideShow

If anyone could advise me on what needs doing to fix this it would be greatly appreciated. You can swap the code and use a complete alternative method if it will work.

Many Thanks Guys!

I think the key is to put them in separate divs. (snippet needs jquery) Look at codepen

$("#slideshow > div:gt(0)").hide();

setInterval(function() { 
  $('#slideshow > div:first')
    .fadeOut(1000)
    .next()
    .fadeIn(1000)
    .end()
    .appendTo('#slideshow');
},  3000);

#slideshow { 
    margin: 50px auto; 
    position: relative; 
    width: 240px; 
    height: 240px; 
    padding: 10px; 
    box-shadow: 0 0 20px rgba(0,0,0,0.4); 
}

#slideshow > div { 
    position: absolute; 
    top: 10px; 
    left: 10px; 
    right: 10px; 
    bottom: 10px; 
}

<div id="slideshow">
<div>
    <a href= "http://www.musicmatters.ie/index.html"><img src = "http://www.musicmatters.ie/images/bara2.jpg" width="240" height="240" alt = "Agents of Shield" title="Agents of Shield"/> </a>
    </div>
    <div>
    <a href= "http://www.musicmatters.ie/about.html"><img src = "http://www.musicmatters.ie/images/bara3.jpg" width="240" height="240" alt ="The Fantastic Four" title= "The Fantastic Four"/></a>
    </div>
    <div>
    <a href= "http://www.musicmatters.ie/singingamach.html"><img src = "http://www.musicmatters.ie/images/singingamach.jpg" width="240" height="240" alt = "Jurassic World" title = "Jurassic World"/></a>
    </div>
    <div>
    <a href= "http://www.musicmatters.ie/contact.html"><img src="bara4.jpg" alt ="Paul Walker in Furious 7" width="240" height="240" title ="Paul Walker in Furious 7"/></a>
</div>

</div>

Reference

EDIT:

ADD these classes to your main.css

#slideshow { 
    margin-top:30px;
    margin-left:auto; 
    margin-right:auto;
    padding-bottom:10px;
    position: relative; 
    width: 860px; 
    height: 470px; 
    padding-right:0px;
    padding-left:0px; 
    box-shadow: 0 0 20px rgba(0,0,0,0.4); 
}

#slideshow > div { 
    position: absolute; 
    top: 10px; 
    left:0px;
    right: 0px;  
}

and rename your div to #slideshow. Put your images in tags and the slideshow will work See here
