Title: Don't return an image url if user doesn't have an avatar

Thanks for writing this gem. I was having the following issue:

If a user doesn't have an avatar, the server will return the `iconfarm` as `0`. The plugin relies on this value to build the url, and was returing an invalid image host (http://farm0.static.flickr.com/).
