How to programmatically determine the default avatar?

Hi all,

I am working on an Achievement that is awarded when you have updated your Avatar (among other things)...

Is there a way to determine the URL of the default Avatar?

Or can I assume that it will always be "anonymous.gif" across different versions of Verint?

Or is there some other way to determine if the user is using the default Avatar without having to look at the AvatarUrl?

Thanks.
