Today I present an easy to use open source gravatar control.
To show a gravatar logo of one of your visitor you'll need only the visitor's email.
I took the source code from the reference implementation advertised on Gravatar from freshclickmedia (see references at the bottom of this article), updated it to match the new gravatar API, and among other things fixed the ViewState implementation.
Basic usage
1) In your project add a reference to the assembly FreshClickmedia.Web.dll
2) At the top of your aspx or ascx page add:
<%@ Register TagPrefix="fcm" Assembly="FreshClickmedia.Web" Namespace="FreshClickMedia.Web.UI.WebControls" %>
3) In your page add this tag where you want the logo to appear:
<fcm:Gravatar ID="GravatarImage" runat="server" Email="thisemaildoesnotexist@thisemaildoesnotexist.com" />
