How to download images from other sites?

Question

JavaScript

Is there a solution for downloading images from web resources by url, and then saving them. The bottom line is that the images are saved on the client.

Answer 1

by "on the client" do you mean the browser?
It seems that the security policy of browsers today will not even allow you to make a cross-domain request and get images without a special header from the server that you are going to "rob". If I'm not mistaken.
You can follow. scheme:
Client <- Your site -> Site "victim".
Those:

$.post('/getImages.php', {
     url: 'http://site.com/images/image.jpg'
}, function (data) {
    // Сохраняем изображения
    // Правда признаюсь - это извращение ;)
}, 'JSON');

<?php
     $url = $_POST['url'];
     $filename = end('/', $url);
     $path = __DIR__ . '/images_cache/';

     file_put_contents($path . $filename, file_get_contents($url));

     json_encode([
          'image' => '/images_cache/' . $filename,
          'filename' => $filename
     ]);
