Gravatar Description

The Gravatar control is an ASP.NET AJAX control that enables you to use gravatar images on your web forms. A gravatar is a "Globally Recognized Avatar" provided by Gravatar.com.


This control is extremely simple to use. The only required property which you need to set is your email. In addition, you can specify the requested size of the image, required rating, default image, and default image behavior.


You can use the DefaultImageBehavior property to control what happens when an email account does not have an associated gravatar. The possible options are:

  • MysteryMan — The same image of a Mystery Man (an anonymous profile of a man) is displayed for all unrecognized emails.
  • Identicon — A different geometric pattern is generated for each unrecognized email.
  • MonsterId — A different image of a monster is generated for each unrecognized email.
  • Wavatar — A different image of a face is generated for each unrecognized email.
  • Retro — A different 8-bit arcade-style face is generated for each unrecognized email.

Alternatively, you can specify a custom default image by setting the DefaultImage property to point at an absolute URL.
