If you fill an URL here, this URL will be used instead of the regular avatar URL, and you will be given an option to select a "mood" for each of your posts. A {{$}} character in the URL will be replaced by the mood index number for each post.%%%
__Example: http://site.url/avatar$.png __
* If the URL does not contain {{$}}, this setting has no effect.
* This does not generate any new images; it only performs pattern substitution on the URL (replacing {{$}} by a number). You need to provide the images yourself.
