Hi a newbie here can someone help with this problem i'm having with the image decscription of my image gallery, when the thumbnail is clicked the description shows up but when using the next and previous button i can't get it to show `//image click

$('.pic img').on("click", function(){
  
    
    img_index = $(this).parent().index();
    $('.pic img').css('border', 'none');
    $(this).css('border','2px solid #4f4f4f');

    $('pic').css('marginLeft', '0')
    $(this).parent().css('marginLeft', '3px');
      
    image_address = $(this).attr('src');
    list = image_address.split('/', 4);
    name = list[3];

    $('#display img').fadeOut(150, function() {

$('body').on('click', '#right', function () {

    var last_index =  $('.pic').last().index();

    if (img_index == last_index) {

        img_index = $('.pic').first().index();

    }
    else {

        img_index = img_index + 1;

    }




    image_address = $('.pic').eq(img_index).find('img').attr('src');
    list = image_address.split('/', 4);
    name = list[3];

    $('#display img').fadeOut(150, function () {

        $('#display').html("<img class='display_img'  src='img/photography/" + name + "'> ");

        $('#display img').fadeOut(0);
        $('#display img').fadeIn(150);

In below code i have change id to class because you cannot have mutliple ids with same name .Then , to get the value of caption i have use $('.pic').eq(img_index).find("div.caption").html() which will give us the description of that particular image only .

Demo Code :

var img_index = 0;
$('body').on('click', '#left', function() {
  if (img_index == 0) {
    img_index = $('.pic').last().index();
  } else {
    img_index = img_index - 1;
  }
  image_address = $('.pic').eq(img_index).find('img').attr('src');
  list = image_address.split('/', 4);
  name = list[3];
  $('#display img').fadeOut(150, function() {
    //added direct src 
    $('#display').html("<img class='display_img'  src='" + image_address + "'> ");
    $('#display img').fadeOut(0);
    $('#display img').fadeIn(150);
  });


  $('.pic img').css('border', 'none');
  $('.pic').eq(img_index).find('img').css('border', '4px solid #18a6ed');

  $('pic').css('marginLeft', '0')
  $('.pic').eq(img_index).css('marginLeft', '5px');
  $(".img_caption").children().remove();
  //get text which is in caption div
  var text = $('.pic').eq(img_index).find("div.caption").html()
  //add that to img_caption
  $(".img_caption").html(text).fadeIn();

});

$('body').on('click', '#right', function() {
  var last_index = $('.pic').last().index();
  if (img_index == last_index) {
    img_index = $('.pic').first().index();
  } else {
    img_index = img_index + 1;
  }

  image_address = $('.pic').eq(img_index).find('img').attr('src');
  list = image_address.split('/', 4);
  name = list[3];

  $('#display img').fadeOut(150, function() {
    //directly add default image
    $('#display ').html("<img class='display_img'  src='" + image_address + "'> ");
    $('#display img').fadeOut(0);
    $('#display img').fadeIn(150);
  });

  $('.pic img').css('border', 'none');
  $('.pic').eq(img_index).find('img').css('border', '4px solid #18a6ed');
  $('pic').css('marginLeft', '0')
  $('.pic').eq(img_index).css('marginLeft', '5px');
  $(".img_caption").children().remove();
  //get text
  var text = $('.pic').eq(img_index).find("div.caption").html()
  //add to div
  $(".img_caption").html(text).fadeIn();
});
img {
  height: 55px;
  width: 55px;
}

.img_caption {
  font-size: 18px;
  color: #cc216b;
