Update – 12 June 2008
An updated version of this post, containing full source for the control and explanation is available here.
I just got myself a freshclickmedia.com Gravatar over at gravatar.com. A Gravatar is a little avatar associated with an email address, and quite a few blogs use them to decorate post comments. Signing up is easy – all you need to do is supply an email address, and image, and give your image a content rating.
The source of the gravatar image tag points to gravatar.com’s image generator and includes an MD5 hash of the email address to prevent email harvesting. A ‘max rating’ parameter prevents the display of unsavoury content.
There are a wide number of blogging gravatar plugins, so I decided to write an ASP.NET custom control to do the job. Here I present the control and its features.
