.factory('gravatarImageService', function(md5) {
    return {
        getImageSrc: function(value, size, rating, defaultUrl, secure) {
            // convert the value to lower case and then to a md5 hash
            var hash = md5.createHash(value.toLowerCase());
            var src = (secure ? 'https://secure' : 'http://www') + '.gravatar.com/avatar/' + hash + '?s=' + size + '&r=' + rating + '&d=' + defaultUrl;
            return src;
