unibox and contact list avatars

From: https://www.uniboxapp.com/faq/contact-list/avatars

  Unibox displays contact images (avatars) from contacts within your address book, from contacts that 
  have a gravatar.com account or its own Domain Avatars service.
  Many people use gravatar.com to associate their email address with a picture. Unibox will check if a 
  picture is available for the sender address of your emails and display it as avatar.
  Unibox provides a backend service, so-called Domain Avatars, to check for icons of the domains of the 
  sender address of your emails. Many company logos such as Amazon and Twitter icons will be displayed 
  as avatar.
  If an address book image exists Unibox will prefer it to the other sources. This way gravatar images 
  can be overridden by adding a contact including an image to the address book. Only if no address book 
  image or gravatar image is available, Unibox will display a Domain Avatar.

Favicon to your Site

Method 1

<!DOCTYPE html 
      PUBLIC "-//W3C//DTD HTML 4.01//EN"
      "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en-US">
<head profile="http://www.w3.org/2005/10/profile">
<link rel="icon" 
      type="image/png" 
      href="http://example.com/myicon.png">
[…]
</head>
[…]
</html>

Method 2

(Discouraged): Putting the favicon at a predefined URI
A second method for specifying a favicon relies on using a predefined URI to identify the image: "/favicon", which is relative to the server root. This method works because some browsers have been programmed to look for favicons using that URI.

Create a 16 pixel wide by 16 pixel high favicon.bmp file in a Program like MS-Paint, Adobe Photoshop, or Jasc's Paint Shop Pro, then use a program (such as the free IrFanView app [for Windows]) to reduce the colors to 16 colors [Image -> Decrease Color Depth], and then 'save as...' to a Windows Icon Format (favicon.ico).
