Answer 1

You can use the HTML5中的download attribute, refer to w3school:

<a href="https://www.baidu.com/img/bd_logo1.png" download="baidu">

Attached is a cross-domain solution

Nginx (Same as Apache):

location /imgProxy {
    resolver 10.0.0.1;
    proxy_pass $arg_url;
}

<a href="/imgProxy?url=https://static.segmentfault.com/v-5922866b/global/img/logo-b.svg" download="logo">segmentfault</a>

Currently only Chrome supports this feature:

<a href="..." download="file.mp4">Download</a>
