Create download link based on img src Jquery

I have several different galleries of images that have image captions. I'm attempting to append a download link of the corresponding image to the end of each of the gallery captions. The download link needs to be based on the img src for each image.
I can get it to append the download link to the caption. However, it's also appending a download icon for each image contained in the gallery on every image caption. Instead of one download link per image.
HTML
<div>
<figure class="gallery-item">
<!-- BoGalleryImg -->
<div class="gallery-icon landscape">
<a href="http://creative.dev.j2noc.com/thehub/wp-content/uploads/2017/10/crkis-2515.jpg" data-rel="lightbox-gallery-1">
<img width="300" height="250" src="http://creative.dev.j2noc.com/thehub/wp-content/uploads/2017/10/crkis-2515.jpg" class="attachment-full size-full" alt="" aria-describedby="gallery-1-823">

jQuery
$(document).ready(function() {
$('.attachment-full').each(function(index, element){
// create variable from img src
var imgSrc = $(element).attr('src');
console.log(imgSrc);
//Append Download Link to Caption
$('.gallery-caption').append('</span>');
});
});
I have been trying to figure this out for a couple days now and I'm so close I'm just not sure how to get it to append only one download icon for the corresponding image. Thank you in advance for any help that can be provided.
My CODEPEN DEMO

Your html is a bit hairy to parse. Here is some jQuery that reproduces your output with the desired icon count:
images = ['http://srsounds.com/j3/images/easyblog_articles/2943/han_solo.jpg', 'https://lumiere-a.akamaihd.net/v1/images/chewie-db_2c0efea2.jpeg?region=0%2C154%2C1592%2C796'];
labels = ['CRKIS-2515', 'CRKIS-2379B']
images.forEach(function(value, index) {
$('body').append("<img src=" + value + " width=350><br>" + labels[index] + " <i class='fa fa-download' aria-hidden='true'></i><br><br>");
$('body').css('color', 'steelblue');
})
If you want to use these icons bring in awesome fonts:
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
There may be other requirements in terms of your gallery layout, but hopefully this will help you get started on a cleaner approach.
If you're having issues adding link attributes to your icons, or achieving additional layouts let me know.
******** EDIT ********
If you want/need to stick with your original approach, then change your jQuery to this:
$(document).ready(function() {
download_ids_hold = [];
imgSrc_hold = [];
$('.attachment-full').each(function(index, element){
// create variable from img src
var imgSrc = $(element).attr('src');
imgSrc_hold.push(imgSrc)
console.log(imgSrc);
//Append Download Link to Caption
$('.gallery-caption').each(function(ind_2, elem_2) {
add_id = 'a_' + Math.floor((Math.random() * 100000) + 1);
download_ids_hold.push(add_id)
if(index == 0) {
$(this).append('<a id=' + add_id + ' download><i class="fa fa-download" aria-hidden="true"></i></span></a>');
}
})
});
for(id=0;id<download_ids_hold.length;id++) { $('#' + download_ids_hold[id]).attr('href', imgSrc_hold[id]) }
});
We track the image sources and download ids, and use them appropriately at the end.

jQuery Get IDs by Class Name

I have a page of about 15-20 YouTube videos I’d like to dynamically update the img src to point to the YouTube hosted thumbnails. From a logic perspective, I want to find every DIV with a class of “videos”, get the ID of that class and update the image source with the dynamically inserted value, e.g., http://img.youtube.com/vi/DbyNtAQyGs/0.jpg in the first example. All IDs are unique because they are the YouTube video IDs and there is only one img tag under each “videos” class.
This code would run on page load so it would have to be pretty fast to ensure the values are set before the browser passes the each img tag in the DOM. Hoping I can get one of those one liners instead of vars and multiple lines.
<div id="DbyNtAQyGs" class="videos">
<img src="" width="212" height="124" />
</div>
<div id="Fh198gysGH" class="videos">
<img src="" width="212" height="124" />
</div>
Current Code
$('.videos img').attr('src', 'http://img.youtube.com/vi/' + $(this).closest('div').attr('id')); + '/0.jpg');

You can use:
$('.videos img').attr('src', function() { return 'http://img.youtube.com/vi/' + $(this).closest('div').attr('id') + '/0.jpg'; })

Loop through the .videos elements:
$('.videos').each(function(){
var $this = $(this),
_id = $this.attr('id'); // Capture the ID
// Construct the img src
$this.find('img').attr('src', 'http://img.youtube.com/vi/' + _id + '/0.jpg');
});
Bonus: chain in the click event for your anchor:
$this.find('a').click(function(e){
e.preventDefault();
loadPlayer(_id);
}).find('img').attr('src', 'http://img.youtube.com/vi/' + _id + '/0.jpg');
So you can simplify your markup:
<div id="DbyNtAQyGs" class="videos">
<img src="" width="212" height="124" />
</div>

How to handle: When image is clicked identical image generated using Javascript

The code below works to make one copy of the image clicked. I am needing the code below to work for multiple images.
For example if I click 5 images on the screen, the same 5 images should generate at the bottom of the page. The user should be able to select 5 out of 10 images. Any thoughts? Thanks!
JS:
function changeImage() {
var imgSrc = 'http://placehold.it/150';
if (document.getElementById('myImage').src === imgSrc) {
document.getElementById('new').src = imgSrc;
}
}
HTML
<a href="#" onClick="changeImage()">
<img id="myImage" src="http://placehold.it/150"></a>
<img id="new" src="http://placehold.it/200">

You can use JQuery clone() function
$('img').click(function() {
$('body').append($(this).clone());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="http://placehold.it/50x50">
<img src="http://placehold.it/50x50/000000/ffffff">
<img src="http://placehold.it/50x50/1C90F3/ffffff">
<img src="http://placehold.it/50x50/F2BB7C/ffffff">

you can use jquery to do that
HTML
<a href="#" id="my-image">
<img id="myImage" src="http://placehold.it/150"></a>
<img id="new" src="http://placehold.it/200" />
JS
$('#my-image').click(function(){
//setting attribute src to be equal as src from #myImage
$('#new').attr('src', $('#myImage').attr('src'));
//returning false in order to avoid default action
return false;
});
So that is it :)
Just remember to put this code after your html or into
$(document).ready(function(){ ..... });
I hope this helps.

jQuery append an img to every div

I am trying to display a thumbnail image with every thumb class, but currently I am getting the output below where the images are looping inside the href instead. The order of div, href and img must not change. It looks something like this jsfiddle but this isn't fully working of course...
currently getting:
<div class ='thumb'>
<a href="#" rel="1">
<img src="">
</a>
<img src="">
<img src="">
</div>
required output:
<div class ='thumb'>
<a href="#" rel="1">
<img src=>
</a>
</div>
<div class ='thumb'>
<a href="#" rel="1">
<img src="">
</a>
</div>
my loop:
var thumbnails = [];
$.each(data.productVariantImages,function(key, val){
thumbnails.push(val.imagePath);
});
for(var thumb in thumbnails) {
$('.thumb').append($('<img>').attr({
"src":[thumbnails[thumb]]
}));
}
am i looping it wrongly?
edit:
The thumbnails are part of a dynamic gallery where basically every time a user choose a different option in a dropdown list, the sources for the thumbs are supposed to change accordingly.
current html:
<div class="thumbnail"><?php
foreach($skuDetails['productVariantImages'] as $variantImage){
if(isset($variantImage) && $variantImage['visible']){
?>
<div class="thumb">
<a href="#" rel="1">
<img src="<?php echo $variantImage['imagePath']; ?>" id="thumb_<?php echo $variantImage['id']; ?>" alt="" />
</a>
</div> <?php }}?>
</div>
sample array of thumbnails:
["http://tos-staging-web-server-s3.s3.amazonaws.com/9/catalogue/apples_in_season.png",
"http://tos-staging-web-server-s3.s3.amazonaws.com/9/catalogue/apples_in_season.png"]
sample output:
<div class="thumbnail">
<div class="thumb">
<a href="#" rel="1">
<img src="http://tos-staging-web-server-s3.s3.amazonaws.com/9/catalogue/apples.png" id="thumb_323" alt="">
</a>
</div>
<div class="thumb">
<a href="#" rel="1">
<img src="http://tos-staging-web-server-s3.s3.amazonaws.com/9/catalogue/apples.png" id="thumb_323" alt="">
</a>
</div>
</div>

You need to use .each function on .thumb. Something like:
$(document).ready(function(){
$('.thumb').each(function(){
$(this).append($('<img>').attr({"src":[thumbnails[thumb]],}));
});
});

your loop is focused on wrong element. You append img tag to the thumb class. So, the img tags inside the same element. You should create div has thumb class inside the loop, and append it to the thumbnail div. That must like
var div = $(".thumbnail");
$.each(imageArray, function(index, value){
var elem = "<div class='thumb'><a href='#' rel='1'></div>";
div.append($elem);
$('.thumb').append("<img />").attr("src", value);
});
It may be wrong but you should watch the thumbnail element. I cannot write the code to test. But I think the logic must be like this.

If you want that exact structure, I made a demo using plain JavaScript. Enter a number and the thumbClone() function will generate that many. You could probably adapt this function with your existing code easily. I'm in rush, it probably needs refactoring, sorry. :-\
DEMO
function thumbClone(qty) {
var main = document.getElementById('main');
var aFig = document.createElement('figure');
var aLnk = document.createElement('a');
var aImg = document.createElement('img');
aLnk.appendChild(aImg);
aImg.src = "http://placehold.it/84x84/000/fff.png&text=THUMB"
aFig.appendChild(aLnk);
aLnk.setAttribute('rel', '1');
main.appendChild(aFig);
aFig.className = "thumb";
console.log('qty: ' + qty);
var thumb = document.querySelector('.thumb');
for (var i = 0; i < qty; i++) {
var clone = thumb.cloneNode(true);
thumb.parentNode.appendChild(clone);
}
}

You need to use each loop which will get each class rather than getting only one class below is syntax of each loop
$(selector).each(function(){
// do your stuff here
)};
in your case
$('.thumb a').each(function(){
// do your stuff here
$(this).append($('<img />').attr('src',[thumbnails[thumb]]);
)};

Looks like you need to create the entire div structure for each image.
Lets create the below structure dynamically using the max length of the image array and add the image src .
var thumbDivStart = "<div class ='thumb'><a href="#" rel="1">";
var thumbDivEnd = "</a></div>";
var thumbDiv = "";
for (i = 0; i < imageArray.length; i++) {
thumbDiv = thumbDivStart + "<img src="+imageArray[i]+"/>"+
thumbDivEnd;
//Here you can append the thumbDiv to the parent element wherever you need to add it.
}

add content through javascript

I am trying to create a page where when you click on any of the three images. It inserts the content into the empty div above the image links.
Here is my javascript code:
<script type="text/javascript" src="js/jquery-1.8.1.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('img').click (function() {
$('.deal_content').append(<img src="deal_content.fw.png" width="587" height="299" alt="Your Deals!" />);
return false;
});
});
</script>
and this is the HTML it is to effect:
<div class="deal_content">
</div>
<div id="imagelink">
<a href="#">
<img src="for_men_btn.fw.png" width="200" height="87" alt="For Men" />
</a>
<a href="#">
<img src="for_couples_btn.fw.png" width="200" height="87" alt="For Couples" />
</a>
<a href="#">
<img src="for_teens_btn.fw.png" width="200" height="87" alt="For Teens" />
</a>
</div>
I wish the new image to be put in the deal_content class div.

In your append method, if you put double quotes around the HTML and replace the current quotes with single quotes, it should work. Append takes a string or a JQuery selector, not markup.

You need to make the element a string in order to pass it through append
$(document).ready(function() {
$('img').click (function() {
$('.deal_content').append('<img src="deal_content.fw.png" width="587" height="299" alt="Your Deals!" />');
return false;
});
});

Considerting this is what you want:
I wish the new iamge to be put in the deal_content class div.
You are almost there:
In the Javascript that you have:
$(document).ready(function () {
$('img').click(function () {
$('.deal_content').append();
return false;
});
});
you need a html() instead of append(). And insert a img tag, and grab the srcfrom the image thatw as clicked on.
$('.deal_content').html("Image \"" + $(this).attr("src") +"\" here: <img src=" + $(this).attr("src") + "/>");
See http://jsfiddle.net/nivas/PA63e/

$('#imagelink').on('click', 'img', function(){
$('.deal_content').append( this );
});
or if you want to duplicate the image:
$('#imagelink').on('click', 'img', function(){
$('.deal_content').append( this.cloneNode() );
});
is that what you want? This way it will only move the images that are inside imagelink element
