You can pull image strings out of a scope variable like this:

 //Embed Parsing + Lookup
 var expression = /[-a-zA-Z0-9@:%_\+.~#?&//=]{2,256}\.[a-z]{2,4}\b(\/[-a-zA-Z0-9@:%_\+.~#?&//=]*)?/gi;
 $scope.url_regex = new RegExp(expression);

 $scope.$watch('post_content', function(){


  } else {
    var post_clone = $scope.post_content;
    var urls = post_clone.match($scope.url_regex);
      var arrayLength = urls.length;
       if (arrayLength > 0){  
        console.log('We have media:' + urls[0]);
    } else {
      console.log('NO URLS in $scope.post_content');
}, true);
