How to add download button to external image on our site
Question
I have a external url image attached with tags in my page. So i tried all methods to add download button to image.

You should try to add a link tag around your image in the HTML :
<a href="link/to/image.jpg" download="name-of-image">
<img src="link/to/image.jpg" alt="your-image" />
</a>

Hi there you can't do it with pure html download attributes.
I don't see clearly how can we do it with js.
For a php solution you will need to curl url of your image and put the image in your server with the same domain name, then you can use the download attributes and it will work
EDIT: For the php edition i can be that : you need to create a files/ folder first
<?php
function grab_image($url,$saveto){
$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // <-- don't forget this
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // <-- and this
$raw=curl_exec($ch);
curl_close ($ch);
if(file_exists($saveto)){
unlink($saveto);
}
$fp = fopen($saveto,'x');
fwrite($fp, $raw);
fclose($fp);
}
$link = "https://images-na.ssl-images-amazon.com/images/I/81tISKde7HL._AC_SL1500_.jpg"; // your link
$temp_match;
preg_match('/(?=\w+\.\w{3,4}$).+/',$link,$temp_match); // get the filename from url return an array
$file_name = $temp_match[0]; //get the name from the array
$path= ('./files/'.$file_name); // create path
grab_image($link,$path);
?>
