Any way to capture a logo icon from a website URL programmatically?

I am engaged in creating activity, where I will show a list of visited websites with its logo and its nickname selected by the user.

eg.

  • Recent Website Visits

    logo1 website1 / alias

    logo2 website2 / alias

    .

    . therefore no

The question is (attached image) How to get the site logo displayed on the left side of http: //?

Like below I want to just grab the icon and save it locally

It's called an icon, and all you have to do is:

  • If there is an icon in /favicon.ico, use it.
  • <link rel="shortcut icon" href="URL goes here" />. HTML <link> rel icon, shortcut icon.
