[Plugin: Incarnate for WordPress] Custom default avatar set?

Genius! I love this plugin!

I did wonder if there might be an option for me to put my own set of images somewhere to be randomly used an avatars for people who leave a comment but don’t have an avatar already? I was thinking it would be nice to have something that matched my blog, rather than a Gravatar logo or little monsters (cute as they are!). There is another plugin that does only this (http://wordpress.org/extend/plugins/ravatar/), but I don’t think that one is being maintained any more.

Anyway,thanks again for a great plugin.
