Download all images from website (JS + PHP)

download.js

var buffer = [];
document.querySelectorAll('img').forEach(function(item) {
  if (item.src){
      buffer.push( item.src );
  }
});
console.log('Total items:', buffer.length );
localStorage.buffer = JSON.stringify(buffer);

// Now grab localStorage.buffer and paste it in PHP

download.php

<?php 

$items = '[]'; // JSON string

$items = json_decode($items, true);

foreach($items as $item){
    $filename = explode('/', $item);
    $filename = $filename[ count($filename)-1 ];
    if ( !file_exists('./downloads/'.$filename) ){
        file_put_contents('./downloads/'.$filename, file_get_contents($item));
    }
}
